MK808 Not Recognised By RockChip Batch Tool - Tried Serveral Guides - Android Stick & Console RockChip based Computers

MK808 not recognised by RockChip Batch Tool - tried serveral guides already
Hello,
I can't flash my MK808 because the RockChip Batch Tool doesn't recognize the device. I tried several guides with no success. I'm on Win7/64
At 1st I followed a guide which I think led me to install the google adb driver. It showed up with "adb devices" but not in the RockChip tool.
I think I was misled here and need the rockchip drivers, don't I?
I downloaded the drivers with Version 3.5 and I also tried the ones which were included in the RockChip Batch Tool (v1.5, v1.6 and v1.8). Windows didn't accept them and kept using the adb or MTP drivers. Now I noticed that in the device manager the MK808 shows as "USB\VID_2207&PID_0001". But in the inf file of the drivers all PIDs were 2xxx or 3xxx. Now just like with the adb driver I added two lines with the ID I got from the device manager. Now the driver is accepted. But I still have no success with the RockChip tool.
I also found a thread which mentions to modify the config.ini of the batch tool but this didn't helped either.
(SUPPORTLOWUSB=TRUE
FULLSPEEDUSB=TRUE)
As I understood I should switch USB debugging off on the device. Than I should go to Settings - USB and click "Connect to PC". Is this right?
Any idea what I might do wrong?
BTW what is the latest firmware for MK808?
thx n rgds
tmg

got it.
Problem was that device was in MTP mode. had to switch it to "mass storage mode". There's another "settings" icon which opens not the standard settinge and there on the "system" tab (?) I could change it. The guid in the web suggest that it could be done in the standard settings, but this didn't worked for my MK808.
usb debugging needs to be off.
At 1st the device is red in the tool. I need to click "switch" to get it green. Wasn't obvious.
1st start seems to take a while ... just came up nice.

[USB Drivers] Galaxy S GT-I9000 (Working on ICS)

Hello.
And bacon and spam:
I've recently upgraded my SGS to ICS (ICSSGS ROM) and started to develop a simple application.
So, now i've got to the point that the emulator starts to show its limitations, so i need to debug directly on the real device.
Well, i've been trying to make ADB recognize my phone, tried several usb drivers from several sites, none of them worked.
After several hours spanking windows, it's finally working (yes! almost 6 AM in the morning!).
What matters:
So, to anybody who have the same problem as i had, do the following:
0. Uninstall any drivers that you've tried before.
1. Extract the zip file that i've uploaded to anywhere you like.
2. Enable debugging on your phone and connect it to PC throught the USB cable
(Just connect it, don't mount)
3. On your computer, click Start -> Right click on "Computer" -> Manage
This will open the "Computer Management" window (it might take some seconds to load).
4. Click "Device Manager". Now you should find your device in the list. It must be really easy to find. It's called something like "GT-I9000" or "GalaxyS" and it has a yellow warning sign next to it.
5. Right click on it and choose "Update Driver Software". In the window that appears, choose "Browse my computer for driver software". It then asks you where is the driver.
6. Click the "Browse" button and choose the folder you extracted from my zip file.
(If you didn't change it, it must be called "Android Composite ADB Interface")
7. Click "Next" and cross your fingers. If you're lucky, it may work for you.
Final notes:
1. I'm not responsible for ANYTHING. Whatever you do, it's your own choise to do it. I guarantee absolutely nothing.
2. This is was tested on Windows 7 - 64 bits with Team ICSSGS RC4.2 ROM and Semaphore ICS 0.9.1 Kernel.
3. Have fun.
4. If you try this, please answer the topic and tell everybody if it's working for you (mentioning your Windows version and what ROM you use).

Missing file when installing driver on windows 7 x64
Hi,
I have recently installed the most recent Dark Knight ICS 4.0.4 build to my Samsung Galaxy S. The ROM seems very good but I'm an android app developer and need to be able to debug my applications on the device via USB.
I have tried the driver provided in the thread which won't install due to a missing file according to the Windows 7 x64 driver install wizard. The exact message is displayed after step 7 and says:
"Windows found driver software for your device but encountered an error while attempting to install it."
"Android Composite ADB interface"
"The system cannot find the file specified".
Is there a file missing in the package? Has anybody managed to get this driver working?
Cheers,
Ben
Does it say that it doesn't find a controller or that is there a missing file?
Anyway, please try this installer and let me know if it works for you:

What's wrong with the Nexus S drivers available with Android SDK?
Google USB driver, R4 developer.android.com/sdk/win-usb.html
The SGS will present it self like that when it is running ICS/CM7/CM9.

Nevertheless thanks for your approach. I'll test if it works with the SDK Updater.
I'm going to test in my desktop this weekend to check if it works with it.
I have the same problem, but with WIndows 7 32 bit. Drivers from discusion doesn't work. Don't you have some for 32 bit?
I found SDK Components on developer.android.com, where is Android driver which suppose to work, but unfortunately ODIN still do not see phone.
I also have the same problem but mine is worse because my phone is completely down after I tried to restore from a GB ndriod backup failure , phone won't boot , cannot boot into recovery only in download mode but no way my 4 x computers would detect the phone now ....tried using heimdall in linux as well as sdb, no go....so sad...help...

Using Google USB drivers finally worked for me. They can be optionally installed with Android SDK using SDK manager (extras). After installation drivers can be found in <sdk>\extras\google\usb_driver.
Just follow the instructions in the first post to find your device from device manager with exclamation mark. Need at least one reboot to work and I also redirected the driver installation process to Google usb driver directory but now ADB finally recognizes my SGS (MyICS, Android 4.0.3).
Edit: Operating system Vista 64-bit
[Currently stuck in "error: device not found" while trying adb push -command. I will update if I find a workaround. Probably something to do with inf-file.]
For alternate .inf -file (optional):
Google "usb-drivers-not-working-after-flash-latest-rom-ota" and see post #12 to see alternative inf-file. Some have managed to make adb recognize the device with that file, but I have at least this far been unsuccessful.
Edit: Problem above was caused by me being stupid and trying to use push in shell, which caused phone unable to locate host system folders. I don't know if that inf file has anything to do with drivers working now, but go ahead and try it if doesn't work with the original .inf
I got my i9000 recognized using the latest drives from the Google sdk

This worked for me
The very important thing is that newest Google USB driver is in
Code:
[B]<android-sdk>/extras/google/usb_driver/[/B]
location, not in
Code:
<android-sdk>/usb_driver
It really makes the difference !
these drivers only worked once...
all the other times killing and starting over adb i was getting error messages like "device not found" and "protocol fault" even though adb devices was listing the device online.
apparently i connected the phone to another USB3 port on my pc (front panel) and that was it!! it now works every time i type adb shell or adb devices.i no longer get any error messages.rather weird
anyway..i also wanted to be up to date with everything so i uninstalled all related software like the older java 6 jdk, Android SDK and the drivers mentioned above.
i followed the procedure below and installed all the latest packages:
latest java 7u5 JDK, the latest Android SDK (nstaller_r20.0.1-windows.exe) then ran sdk-manager and loaded http://developer.android.com/tools/extras/oem-usb.html#InstallingDriver google USB drivers rev 6. then installed these drives so i got the ADB composite interface on my device manager and it all works fine now.
I recenelty installed latest ICS , and SDK recognizes my phone as ACER ADB , when I'm pretty sure its a Samsung I9000 . I tried uninstalling the ACER ADB and install the one that the guy posted in the first post , and it didn't work , it said this driver is not compatible , oddly it reinstalled ACER ADB though. I can't even uninstall it at all , I removed all my Samsung drivers , and everything else I installed for Samsung , and its still there , I even tried removing the GOOGLE USB drivers , still there.
Neendless to say that the phone doesnt connect to the PC at all even though it says everything is alright. For example i got ths gPAD app , which uses the USB with Debugging to turn the phone into a mouse , but it says its not connected even though it is.

[Q] Extreme Driver Fail

Hello Everyone,
----------------------------
Nexus 7 Driver Fail
----------------------------
I was Unable to install drivers on Windows XP (ADB and Fastboot Drivers do not load). Every step has failed and multiple drivers fail to install with Code 18 and 28. I’ve tried just about EVERY Tool Kit available out there and searched fourms, still no positive results. If anyone out there may have an answer please feel free to drop it in here, I greatly appreciate all your help. Thank you.
Here is a list of what I have done thus far:
- Rebooted the computer after uninstalling devices with USB Deview before
continuing on to the other steps
- Uninstalling and manually deleting driver from the registry
- Unplugging and repluging the device while watching
the device manager (The device shows up as other devices, Example: nexus and MTP)
- I tried disabling auto driver configuration by Simply pressing the "Disable Auto Driver Config" button and then
changing the settings accordingly
- Registry cleaning
- Removing and manually adding to windows driver folder
- Trying on different User accounts from Admin to guest
- Used Android SDK manual driver installation
- Unplugged the device and Launched USBDevice
- Used USBDeview to uninstall any;
- Android ADB Interface device's
- Samsung USB devices
- Google USB drivers
- ANYTHING else you see that resembles your Nexus.
- Looked for devices with Vendor ID's:"18d1"or"04e8"
I then right clicked these devices, and selected the option to” Uninstall Selected Devices"
-Downloaded The official Asus USB driver off of Asus actual support base
And it said the following: an error occurred during the installation of this device The Parameter is incorrect.
Have I missed this action:
Download the drivers from Asus and unpack them to their own directory.
Connect the N7 with USB debugging enabled in "developer options"
Open Device Manager
Locate the N7
(from here my xp knowledge is rusty)
Right click on the N7 and select properties
Find the option to install/update drivers, Take the option to specify the driver directory where you unpacked the download, ensure that include sub directories is ticked and that should install

I tried the same steps.
I even tried using Android SDK, Universal Naked driver
Still no luck
N7 running 4.2.1 stock

No ADB mode, driver issue?

I'm Italian, sorry for my English.
A few days ago I unlocked the bootloader via Toolkit, rooted and flashed the TWRP recovery _.
But I had hard difficulty:
After driver installed, I unlocked bootloader, enable debugging and then NOTHING!
In practice, the N7 was recognized by windows 7 64bit only in FastReboot mode ..
I tried in every way possible, deleted and reinstalled the driver 50 times, restored windows to a previous point, installed the drivers manually tried without toolkit, but how ADB just do not want to know.
For hours I was still with the bootloader unlocked but without root, until came to my rescue a friend with another notebook but same windows 7 64. Load the Toolkit, install the drivers and everything goes perfectly, I do everything in 5 minutes.
On my laptop there is always the issue driver ADB, in the future I still need my PC recognized the N7 in ADB, how can I do?
One thing that I think is not well understood is that there is no "Generic Class Driver" for ADB nor for fastboot...
... even though the very driver that works for one mode (or phone/tablet device) may be perfectly fine with a different device. The wire protocol for both fastboot and adb are extremely simplistic.
So, what that means is that if the Hardware ID used by the USB device endpoint registers on the bus with a different VendorID/ProductID, Windows will (correctly) not use a previously-installed ADB driver, or previously installed fastboot driver - even though they would probably work just fine.
Here is an example. The Nexus 7 registers the following Hardware ID when ADB debugging is turned on in the OS:
USB\VID_18D1&PID_4E42&REV_9999&MI_01
USB\VID_18D1&PID_4E42&MI_01
On the other hand, if you are using TWRP, it's adbd daemon shows up on the PC as:
USB\VID_18D1&PID_D001&REV_9999
USB\VID_18D1&PID_D001
This means that you might need to install a different driver for using the ADB with the OS, and a different driver for ADB under TWRP - even though it is exactly the same hardware on the other end of the cable! In the absence of a generic class driver for a given USB endpoint, Windows tries to match drivers in it's local (& internet) database based on this VID/PID pair.
If you have a look at the [ADB/FB/APX Driver] Universal Naked Driver 0.72 thread - and download it and have a look at it's included "android_winusb.inf" file - you will see literally hundred of different VID/PID pairs in the driver's android_winusb.inf file in the installer package, corresponding to many hundreds of phones/tablets. Same driver with hundreds of devices listed as compatible.
In the past I recall taking the Google (SDK) USB driver, and manually editing into place matching VID/PID pairs for a HTC phone into the .inf file. It worked perfectly; I probably flashed that phone hundreds if not thousands of times using the Google Driver (My PC is a Windows 7 Pro x64 machine btw).
Anyhow, I have pulled this stunt twice now - once editing the .inf file for the Google Driver, and I did it once with the Universal Naked driver too. You can choose which driver you want to start with.
If you want to give it a roll, you can start with any of those three drivers:
- Google (SDK) USB driver
- XDA "Universal Naked" driver
- Asus Nexus 7 USB Driver (Look under Download)
Note that since you are using W7 x64, make sure that you add each new entries to the .inf file twice - once in the ".NTx86" section, and duplicated again in the ".NTamd64" section. When editing .INF files, make sure to use an editor which preserves simple text file formatting - use "notepad", not "wordpad"
If you want a reference for what values to use, see the bottom end of this post. You should see exactly these same values in your Device Manager, however.
Note that if you see the device show up in the Device Manager as being correctly identified and marked as "working normally" - but it doesn't work - you should probably remove that driver and re-install from a different driver package.
This would certainly be the case for any drivers you saw associating with VID/PID pairs that look like:
VID_18D1&PID_4E40 bootloader/fastboot
VID_18D1&PID_4E41 single adb
VID_18D1&PID_4E42*&MI_01 composite adb
VID_0955&PID_7330 avx mode
VID_18D1&PID_D001 adb in TWRP (maybe CWM too, I didn't check)
That's a lot to throw at you, especially with Italian <=> English in the mix.
Feel free to ask questions.

Hello,
I tried to follow your advice but I have not solved.
I'll explain what I did, so you can correct me.
-Uninstalled previous drivers (from device manager, control panel)
-Restart the PC
-Modified the inf file. Package Asus Nexus 7 USB driver (ntx86 and NTamd64 sections) attach screenshots
-Linked N7 (usb debugging actived)
-Found portable device in device manager, update drivers manually from the Nexus 7 Asus USB drivers
I tried to change also too XDA "Universal Naked" driver by following the same procedure.
I tried to create another account on my pc, but no ADB!

Did you update to 4.2.2?
The is something to do with adb in that update, needing a password or something. I am not sure but if you did update you might want to check that.

Use "Google USB drivers" you get after you install from here http://developer.android.com/sdk/index.html
Its drivers work with 4.2.2
I got 4.2.2. rooted with ADB working now via only this and no other method
No problem with adb in 4.2.2... I tested yesterday (no need psw too...)

Is this the only device which shows up in the device manager? The "Portable Device" is either the MTP or PTP endpoint - not ADB. The latter (adb) should show up elsewhere in the device manager.
You should certainly NOT be trying to install fastboot/adb driver on MTP/PTP endpoints!
I think perhaps I am not understanding because I am guessing at certain details.
Q1) Do the drivers appear to install correctly?
Q2) When you have the N7 in the corresponding mode - whether or not you observe (device manager) "working normally" or "unknown device" - do you see the following Hardware IDs showing up in the device manager?
Bootloader Fastboot Mode:
USB\VID_18D1&PID_4E40&REV_0000
USB\VID_18D1&PID_4E40
OS adb:
USB\VID_18D1&PID_4E42&REV_9999&MI_01
USB\VID_18D1&PID_4E42&MI_01
TWRP adb (Possibly also CWM adb, I haven't checked it) :
USB\VID_18D1&PID_D001&REV_9999
USB\VID_18D1&PID_D001
Q3) I presume you went through the same install sequence on your PC that succeeded on the other laptop - in the event the problem is a hardware problem, did you try a different cable or USB port on your PC?
Q4) When you remove drivers, are you requesting that the drivers be removed from the PC?
The 4.2.2 authentication issue might be an issue (although I suspect this is a adb program version issue, not a driver version issue. In any event, it wouldn't effect the behavior of adb in TWRP/CWM.
Sorry for all the questions.

When the drivers are not installed and I connect to pc N7, is only recognized as a portable device, then later recognized as Google Nexus 7.
To install the drivers (modified as described) I click reinstall driver, then later recognized (if connected to pc in android mode, with usb debugging actived) as Android Device in another voice, ADB interface. But is not recognized by the toolkit under adb devices, and even when I try using cmd.
1-When I install the drivers. seem to be installed correctly.
2-Sorry, where can I find Hardware IDs in Device Manager? What is the difference between OS adb and TRWP adb?
3 - In other pc (with same N7, same cable, same driver, same toolkit) I had no problems. I tried to change only the USB port.
4-I uninstall the driver from device manager (uninstall voice) and ask to be also uninstalled software from the PC
In some Italian forum, I found people with the same problems.
Solved by formatting PC. I would not do that ...
Thanks for your help, sorry for my English and my limited skills

I tried sdk but I have not solved.
I use Android 4.2.1. I'm having problems with the update! I can not update OTA (N7 stuck under the impending reboot). I also tried to download the zip file to upgrade the memory and flash it from recovery but the installation is not completed (error 7 build.prop).
I also tried to flash the factory image 4.2.1 (keeping userdata) and start again. Nothing, same mistakes!
Too many problems!

(Note I attached some pictures below)
From the Device Manager:
- Select the Device in question by right-clicking. Choose "Properties"
- A window with three tabs will appear: General, Driver, and Details. Select Details
- The "Property" combo-box-selector has 20 or 30 items - the 2nd one in the list is Hardware Ids. I attached two pictures from Win7-Pro-x64 (below)
But note as I said before: You should NOT be seeing the ADB endpoint under "Portable Devices" - if ADB Debugging is turned on in the OS, you should see it under "Android Phone" or something similar. In any event, the hardware Ids will identify it exactly
Marco16V said:

Well, as far as the behavior of the USB driver on the PC, almost nothing. Unfortunately - for better or for worse - both TeamWin (TWRP) and CWM authors put their ADB interface on the bus with the VID/PID pair of USB\VID_18D1&PID_D001, whereas the OS puts all its USB interfaces on 18D1/4Exx.
So, even if you get a driver installed for the OS "adb" mode (say by using the Google SDK USB driver or the Asus Nexus 7 driver), it won't work for the custom recovery... unless you fix up the driver installer package to have the matching VID/PID pairs (18D1/D001) in the .INF file for that driver.
I think folks find this confusing - they think, "wait, I have a ADB driver installed" - why does it not work?
OK, there are a couple more things to try (at least before I give up). Roughly they try to answer these questions:
Q1) Is this a toolkit issue, or a driver issue?
Q2) Is it a prior driver you installed that you are not observing that is causing the problem?
The first one (Q1) is easiest to diagnose: when your PC Device Manager indicates that a device is "working normally" - AND THE VID/PID ID MATCHES WHAT YOU SHOULD EXPECT FOR THE MODE THE TABLET IS IN (regular OS, recovery boot, fastboot mode), can you communicate with the device from the Windows command line? e.g.,
Code:
C:\foo> cd C:\blahblah\sdk-platform-tools-directory
C:\blahblah\sdk-platform-tools-directory> fastboot devices
or
C:\blahblah\sdk-platform-tools-directory> adb devices
If you can communicate with the tablet from the command line - your device ID will be printed by the above commands, then you don't have a driver problem at all - there is something screwy about the way your toolkit is installed.
OK, Q2 -
When Windows installs a driver, it caches it into a kind of database. I suppose it is possible that a prior driver installation might be causing trouble. You can observe - from the device manager - all the drivers that are installed - even for devices that are not currently connected to your computer.
This is done by setting the "devmgr_show_nonpresent_devices=1" environment variable. It can be done semi-permanently this way, or for a single invocation of the device manager this way..
See the third image attached (devmgr-all-devices.jpg ) - it is my computer in that "show all devices" mode. See all that rubbish in there? It's from other Android devices (HTC, Samsung, etc).
You can walk through each one of those - even the devices that are not currently attached - and inspect the VID/PID pair to see if they happen to match the values that you are expecting to see for the different operating modes on the Nexus 7. I'll leave it up to you whether you want to do this or not; it is a bit tedious. Just don't start deleting drivers willy-nilly if you don't know what they are associated with.

[Q] ADB drivers not working

Hello. Im new to the Nexus 10. I downloaded skipsoft Android toolkit, installed adb drivers in the package and rooted the Nexus and installed recovery..it was easy using the toolkit. So the ADB drivers must have worked- at least in the environment it is used in to do these things. But these drivers dont work to transfer files between the nexus and the computer running winxp. I have USB debugging and PTP, have tried every other dirver package that has been mentioned on all available forums, have tried different usb ports, different cables etc. n my computer the device is recognised as a Nexus 10 but clicking on it gives a blank page, so cannot see the Nexux files. WTF this is driving me mad. Any ideas?
Re
Hi Ghosta,
Are you using a USB 3 port? as i have had many strange issues with these the ports. The issue is caused by one of the intel drivers cant remember exactly which way but there is no easy way to fix this. If this is your issues i would try and find if you have a USB 2.1 port you can use or the Esata ports on laptops tend to be usb 2.1 inside...even though they dont look like it haha
Hope this helps

Hello. Im new to the Nexus 10. I downloaded skipsoft Android toolkit, installed adb drivers in the package and rooted the Nexus and installed recovery..it was easy using the toolkit. So the ADB drivers must have worked- at least in the environment it is used in to do these things. But these drivers dont work to transfer files between the nexus and the computer running winxp. I have USB debugging and PTP, have tried every other dirver package that has been mentioned on all available forums, have tried different usb ports, different cables etc. n my computer the device is recognised as a Nexus 10 but clicking on it gives a blank page, so cannot see the Nexux files. WTF this is driving me mad. Any ideas?

What does Device Manager show? Device name, its Properties and exclamation mark?
You do know that if your device has a "password" then you must be logged in to see its contents.

Thanks for the replies and suggestions. All shows up OK in device manager, the device is not password protected, and the laptop has usb2 ports. I had another try today, after connecting the nexus it shows up in my computer as a camera, labelled nexus 10, with the camera icon. When I click on the icon it opens a special folder, must be a camera folder and the camera and scanner wizard starts. After a while it detects the photos on the nexus ( I have loaded a lot on it via USB otg using flash drive ), but thumbnails of the photos are not downloaded as I usually see when I connect a camera. The wizard downloads photos back to the computer, but each photo is about 18 kB instead of the 2 mb they originally were. So it appears a connection is happening, but a very strange one. I don't like to be beaten on problems like this one, but searching the net has not given me any answers, and I don't understand the android system well enough to know what to try next.
I think your device is working. If you connect it up as it now is and then go into Settings > Storage and tap the top RH corner menu you get the USB Computer Connection and select that and change it to MTP you should find it is now visible in My Computer or after auto install of the driver it will be visible. I'm brain dead - you said you had a PTP connection!

No PTP conection or MTP connection either. The Nexus also shows up in Device Manger under Imaging Devices when USB deugging is on, which is causing the camera and scanner wizard to start, although it doesnt work properly. When i disable it nothing happens at all. No idea where to go from here.
There is or was an issue with XP see http://forum.xda-developers.com/showthread.php?t=2305943

Thanks for the suggestion, I had already tried that but I did it again just to make sure. It did not work for me.
Have you tried following the driver install guide from Wug's toolkit? I've never used Skipsoft's but if it doesn't have you delete old drivers properly it's possible there's some old or corrupted driver sticking around from all the installs you've done. If you follow Wug's guide exactly you should end up with the only the correct drivers installed. Also, what ROM and kernel are you using? It's possible the issue is there.

I used a program called usbdeview to uninstall every USB driver with an "android" or "adb" description which should have cleaned up my drivers? Then after reinstalling drivers I tried again no difference. I ran android-tools and can push and pull files to and from the computer and nexus, (from command line) so I believe I have eliminated hardware problems and software problems on the nexus. This leaves the computer, which works perfectly with my other android devices running 4.1.1.
Just in case this helps. In usbdeview I have 5 nexus 10 entries. They all have the vendor id of Google 18d1 and a unique Product ID . Which driver connects is related to the device settings:
PID Device settings
4ee1 MTP
4ee2 MTP + USB debugging
4ee5 PTP
4ee6 PTP + USB debugging
d002 USB debugging
With the device connected I can change settings and see the change in connected driver in USBDeview.

This info does provide me with some way forward. With USB , when connected ptp I have a nexus 10 USB composite device and a nexus 10 digital still camera connected with the green light in USB deview, and also a blank device name, connected, description android composite device with a purple light. I'm guessing purple means not working. But changing drivers does nothing to change the purple light. Switching to mpt gives an additional blank name Google nexus adb interface also with purple light shown as connected. All connected devices show vendor 18d1. Drivers tried 1) clockworkmod (supplied with skipsoft); 2) naked drivers 3) Google drivers. Any clues what to try next?
2 things to check. I just tried running usbdeview from Wug's toolkit. It was v2.0 and wasn't the same as the version I have installed v2.3 - and there have been a significant number of changes. If you have XP pro x64 then you must use the x64 version of usbdeview - again I think Wug's may only ship with 32 bit usbdeview http://www.nirsoft.net/utils/usb_devices_view.html You will also find an explanation of the coloured radio buttons.
If you find you need to update usbdeview then I would suggest you uninstall the device drivers (instructions in Wug's toolkit?) then new drivers from http://developer.android.com/sdk/win-usb.html#top and follow the linked install instructions.

I gave up completely on this, and connect via wifi using ES file explorer. I bought my wife a new tablet an Acer Aconia A1-830 and it has the same problems, impossible to connect via ADB, with exactly the same symptoms. Yet our phones connect via ADB without a problem, but both are Androild 4.1 or earlier and the tablets 4.2 or younger. Obviously an Android generated problem that arose when 4.2 was released and on which has no fix.

Nexus 6P won't install on any system

My dad has a Nexus 6P.
When he connects it to my Windows 10 PC or his own Windows 10 laptop, nothing appears in Computer (any USB mode on the phone).
Device Manager shows a yellow exclamation mark next to the device.
Trying to reinstall shows that an error occurs whilst installing 'MTP Device' (service installation section in INF invalid).
I have tried installing the standard Android USB drivers, no luck.
I've tried with and without USB debugging mode enabled.
Any ideas?
Is the device having any issues? Like is it boot looping or just dead?
If not, it definitely sounds like a driver issue. Open up your device manager and delete any Google / Android drivers and then reboot the PC. That part is pretty important. PCs can be a little wonky with drivers. After that install them via the method posted in Heisenberg's guide. Reboot the PC again and then try.

There are no drivers to uninstall in Device Manager. If I right-click on the (exclamation mark) device in question, I simply get 'Remove', which 100% doesn't uninstall drivers, presumably because no drivers are installed.
Also, the instructions there require a load of stuff (CMD, platform tools, Android debug bridge and all that rubbish), just to install the drivers. I doubt it's that complicated.

I've given you the tools to get it up and running, whether you choose to use them is up to you. If you read the guide, you'd see that you don't need to install the entire SDK. It's one of the first things mentioned in the drivers section. Good luck.
Edit: Read your post again. Seems you're a little confused. CMD is a program already on your Windows PC. You must use it in order to use fastboot. Fastboot and ADB are literally the drivers you need to install. Not "rubbish." Read that guide and take it to heart. There's a lot of learning ahead for you, no offense.

Even if you don't wan't or need ADB/Fastboot, a link to the standalone USB drivers is provided in the guide. If you still have issues, an existing driver installation is likely causing the problem. There is a free tool called USBDeview you can use to get rid of the conflicting drivers.

If you just want to be able to transfer files back and forth between computer and phone you can try installing Huawei's Windows software which should download necessary drivers. I didn't personally find the software all that useful but it's another option if you aren't looking to do anything complicated with your phone.
