[Q] ADB not showing device - Nexus 4 Q&A, Help & Troubleshooting

Hi, my problem is this: my phone is recognized as an ADB device but I cannot see it under adb devices.
Currently running PA RC2 3.99
Fastboot and Recovery do recognize it but ADB does not.
I have the drivers from here installed them as described in the instructions with uninstalling + deleting the old ones and rebooting.
I also have the most updated version of ADB from Android SDK.
One weird thing is that if i uninstall + delete the current drivers and try to install the ones i got from the SDK and not from the thread I mentioned then it does not install them. So maybe that is where my problem...
Any advice??
Thanks in advance.

Did you enable usb debugging?

Also check that you have an option selected under Settings>Storage>USB Computer connection, not having either MTP or PTP selected there will also bork adb.

If you still can't get it to work, try Koush's universal drivers: Link

still not working...
1. Yes, usb debugging is on.......
2. Already tried toggling MTP/PTP/None - When on MTP driver installs successfully but I cannot see the device under adb devices. on the other two options (PTP/None) I am unable to install the driver (tried both the ones on XDA and the ones from MDK)
3. Tried Koush's universal driver - on PTP/None still not able to install drivers. On MTP didn't do much except for changing device name from Android ADB Device to Google Nexus ADB Interface
Thanks for all the quick replies,
Any other suggestions???

what does it say when you issue the "adb devices" command? Please write it out here so we can help you. Does it say "device offline"? If yes, then your device is not registered by digital fingerprint by Android SDK.

Ok, so I'm with my Nexus connected as an MTP device, with the driver from XDA installed (see attached image), USB Debugging enabled:
Code:
C:\>adb kill-server
C:\>adb start-server
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
C:\>adb devices
List of devices attached
C:\>

Any advice???
Anyone has any advice??
I really have not idea what to do. Tried everything...
Thanks

Works on a different computer
I've connected the phone to my borther's PC and installed the drivers from the SDK. It worked without any problem.
I really can't figure out why it's not working on my laptop.

[Solved]
OK...
So as I said before I tried connecting when PTP is checked and when neither PTP nor MTP are checked and on both couldn't install the drivers properly (neither from xda nor from sdk).
What worked for me:
1. Uncheck both PTP & MTP
2. Device Manager -> Nexus 4 -> Update Driver Software -> Browse my computer for driver software
3. Now instead of browsing to the location I went to "Let me pick from a list..."
4. It should show a list of devices/manufacturers. Clicked "Show All Devices"
5. On the bottom right click "Have a disk"
6. Point to the android_winusb.inf file from Android SDK
7. Choose Android ADB Interface from the list
8. Let driver install

[Q] Windows ADB USB drivers?

After enabling USB debugging on my Nexus 7, I still can't get "adb devices" to list my Nexus 7. I also tried switching its USB connection type from "media" to "camera", to no effect. I have Windows 7; I see a "Nexus" device under Other Devices in my device manager, but when I try to install the Google USB drivers from the Android SDK, Windows refuses to take it.
This is going to make development difficult Anyone know where I can find working USB drivers for Windows 7?

If you have updated the drivers from the SDK, then your problem is probably coming from the cable.
PS: Try not to use an extension cable
When I have had this problem in the past I have found that installing PDA net solves it.

You may try to use device manager to solve the issue.:
Firstly please connect your Nexus 7 to you computer using the USB cable
included in the box.
Then on the tablet,
choose "Settings" -> "Storage" -> open the menu -> choose "USB computer connection" -> choose "MTP" or "PTP".
On your computer,
1. Control Panel -> Hardare and Sound -> View devices and printers
2. Click on Nexus.
3. Click on "Hardware" tab
4. Click on "Properties"
5. Click on "Change settings"
6. Click on "Driver" tab
7. Click on "Update drivers".
I'd suggest that you repeat these steps for both "MTP" and "PTP" connection types mentioned above.
Then on your computer, run "adb devices", the Nexus 7 would be listed in the
output of the adb command.
Enjoy.
Works with PTP mode - MTP mode doesn't
just for future reference...
By default it uses the MTP mode for USB. ADB is not working in this mode, even after i follow all the steps in above post.
Change it to use PTP (Camera mode), and ADB works !! go figure.
driving me crazy too.
First, windows did not recognize the thing in AdB mode. I managed to get around that with PDA net. But in cmd mode running "fastboot oem unlock" it just sits there saying "waiting for device". Also switched to both usb modes under "storage" as well as tried all usb ports on my pc (running Win 7 64bit). Using original cable.
Any other clues on what to do next?

ADB and fastboot may have two different drivers, this is the case with most other devices.
Anywho here's a link to the all inclusive driver bundle. Drivers was one of the reasons I only use a linux distro these days.

Still nothing. Deleted the drivers, and it obviously installed the new ones, since the name under the "device manager" changed. I go to the Android sdk and it still says waiting for device. Is there different versions of fastboot? Maybe its the wrong command? (fastboot oem unlock)

Oh and fastboot is not available during normal operations and it has to be booted into the bootloader to use fastboot. Try using adb reboot bootloader and then when it restarts fastboot oem unlock.
I'm in the exact same situation
I'm having the same problem. I'm not exactly sure how to use the Naked Drivers pack. Can someone advise?
Easy as ADB...
Use the step by step instructions in the Nexus Root Toolkit found here;

Set it to ptp mode, install updated sdk, and you will find proper adb driver in extras/google/usb-driver directory. After those steps adb started to work in my case' no need for third party downloads.

I've been having the same issues with all of the new android devices I've tried to use adb on my computer for. I as able to make them work by manually installing the drivers in device manager. When you choose browse for drivers manually you can look through pre installed drivers and select adb interface and manually choose the drivers for adb and fast boot. Only issue I have is that it won't give adb root access and says rot is not available in production builds. Not sue if that's related or not.

Windows 7 - Nexus 7 ADB Recognition
For me, like others, choosing either MTP or PTP from the Nexus 7's USB computer connection options didn't solve the issue. Updated to the latest version of the Android SDK Tools within Eclipse [version 20.0.1], and even uninstalled and re-installed the Google USB Driver [Revision 6] within the Android SDK manager, but no luck.
What ended up clearing the issue for me was to go to Computer Management, find the Nexus device with the question mark next to it, update the driver by browsing a location on the computer, browse to the location on your computer where you saved the Android SDK [the one with the following directories: add-ons, docs, extras, platforms, platform-tools, etc], and choose that very folder containing those folders I mentioned. It should search for a while then ask you whether or not to install some Asus/Google driver.
After installing that driver, my N7 was recognized by the "adb devices" command.
NOTE: Turns out when I updated the driver, my N7 was in PTP mode, and when I switched it to MTP mode, it was no longer recognized under adb devices. adb kill-server then adb start-server should get it recognized again when you switch between MTP and PTP.
Hope this works for all of you out there, like me, who really didn't want to take the 3rd party software route to overcome this problem.
Cheers.
ADB driver
Try to root toolkit from Wugfresh

There is a very complete and usable guide to install ADB driver for most version of windows (XP->win 7).
You don't have to unlock or root; just use the interactive guide for driver install.

i'm having the issue with the mtp not being recognized in adb. can you be more specific in the adb kill-server and adb start-server.

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.

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 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

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.

Using Windows 7 x64 Ultimate and Nexus 4 - Stock 4.2.2
Any help would be appreciated. Thanks.

I had sort of the same problem, try uninstalling the driver in device manager, then unplug and replug your USB. Then when you plugged in the USB go to device manager and right click on the device and click scan for hardware changes. See if that works.
I'm not sure if this is a problem caused by windows update or the new updated SDK, but it has been a big problem for me.

Thanks for the quick reply.
I tried your suggestion but it did not solve the problem. After re-plugging the USB, Windows listed the device as "Nexus 4" and did not find any drivers for it. I manually installed the Naked Drivers (proven to work on my laptop and desktop) but still facing the same problem
I really do not want to reinstall Windows!
Thanks.

OK try right clicking on the the device in device manager and choose update driver, then Browse my computer, then let me pick From a list of devices. After choose have disk on and find the file where your USB drivers are and click next. It may prompt you that windows can't verify the publisher Just click install this driver software anyway.
See if this works.

I have tried installing the drivers from the latest SDK and also the "Naked Drivers" found here: http://forum.xda-developers.com/showthread.php?t=1996051
Still have the problem.

Try pointing the path to the Google drivers in the android-sdk in device manager and not the naked drivers.

This is what I did and waited for the PC to install the adb drivers.
I plugged the phone in and with the USB plugged in turned it off while holding the volume up and down keys. This made my nexus 4 go into download mode and the PC automatically installed the adb drivers. After I just unplugged and held the power button to restart the device hope this helped.

When you uninstalled what's there now, you did make sure to check the box that will remove the old drivers from your PC?
Just in case, HERE is another source for the drivers.

Thanks to everyone for their help.
Just to confirm I have already tried:
Uninstalling the ADB driver via Device Manager and selecting "Delete the driver software for this device" and rebooting.
After reboot, Windows could not locate any drivers and I manually selected the drivers found inside the SDK (08/27/2012,7.0.0000)
The device shows up on Device Manager as working but does not work with adb commands. However, fastboot commands work!
I tried the above with the Naked Driver and had the exact result.
If I boot into the bootloader, I am able to run fastboot commands perfectly!
I have already ruled out my USB port as it works perfectly on VMware.
I am thinking my Windows 7 is messed up somehow and re-installation is looking like the only solution :crying:

4.2.2 requires updated adb and fastboot. It looks like you have an older version.
Click on the ota help desk link in my signature. The new version is attached to the first post. Replace the old adb and fastboot files with the new ones. Then try again.

Thanks. I tried version 16.01 and still have this problem.
The problem is whenever I uninstall/install the ADB driver or disconnect/reconnect the USB, **ONLY** the "Nexus 4" appears on the Device Manager which I manually install the ADB drivers to. There is not a second "Nexus 4" on the Device Manager for the MTP or PTP.
On my laptop when I remove all drivers and reconnect the USB cable, I always see 2 "Nexus 4" listed on Device Manager. One for the ADB interface and the other for the MTP or PTP.
Please help!
Any ideas please?
Any Solution to ADB connection problems?
Hi was there any solution to this, as I seem to have the same issue.
I have tried different drivers and MTP & PPP modes as well as loading the PDAnet drivers and software.
Each time now I take care to remove all the drivers and also delete the drivers in all modes (Android running and Bootloader running)!
MTP & PPP load different copies of the drivers.
I can get either "Nexus 4" showing up in the device driver or "Google ADB Interface" or Android ADB interface" according to the driver loaded.
I can see the device when Android is running ie "ABD Devices" gives me the serial number and connected, then I can send an ADB command "adb Reboot-bootloader" the Nexus then reboots into the bootloader screen, the device driver changes to the bootloader driver (installs if not installed) however then I loose connection to the Nexus phone! "ADB Devices" returns none connected.:fingers-crossed:
I also tried unplugging and plugging back in the phone in bootloader mode but do not get adb to see the handset or it to react to commands.
I'm just about ready to try a toolkit to see if I can get past this roadblock!!!
Current computer is Win7-x64
This weekend I will try on a different computer.....Win8-X64
All comments appreciated
That's because you cant use adb when in boot loader. You use fastboot

I have same problem on my work laptop DELL when my custom desktop machine works just fine with both Nexus 4 and 7. :/

[Q] ADB not working in MTP mode

I'm wondering if anyone has run into this. ADB works fine if I have my phone connected and set to PTP. But if it is set to MTP, adb devices returns nothing connected. MTP itself still works fine to copy files over, and device manager shows the Android ADB device. It's not a huge issue to need to switch it, but it would be nice if there was a simple fix.

3 possible steps:
i) update SDK manager on your computer
ii) check USB debugging is..... well......checked in the phone settings
iii) update the drivers ( SDK manager or Google platform)
Another possibility is to ask your question in the window "search this forum of this thread.
Good luck

Hmm, it works fine for both of mine. I'd say try to uninstall and delete your ADB drivers, and reinstall them. Follow this thread

Hey, while your reply was very informative and useful, you did not read his post properly. ADB works for him only in PTP mode. MTP doesn't work.

As surprising as it might be I did read the post.
My answer is based on my own experience. The Nexus 7 was seen in PTP mode but not in MTP.
To address the issue, after a thorough reading in the XDA forum and thanks to the knowledge of our Forum members, I updated the SDK manager and re-install the drivers.
Hope I answer your concern.

Ah, my mistake. I'm sorry!
I did try searching but most of the posts I found were eith er than MTP was not working at all or ADB was not working at all.
I have uninstalled and reinstalled the ADB driver, but I will try completely removing the SDK next.

This is 99% a driver issue.
I had a similar experience when first setting up my n4.
Debugging on = adb but no mtp
Debugging off = not and obviously no adb
I uninstalled the adb drivers where possible.
Plugged in with mtp mode on and debugging off
Let it automatically install mtp drivers
Switch debugging on
Wait for it to install what it can by itself then manually install the adb driver
Results in fully functional adb & mtp

Well, uninstalling the SDK did not work. I was able to get it working. After uninstalling the ADB drivers and plugging the device back in I saw that the device was still showing up as the ADB interface. I repeated the process a few times and it eventually stopped appearing. After that I reinstalled the driver and everything seems to be working.
i have the same problem
everything works, including PTP, but MTP refuses to work
ther's no error, no missing driver, it just don't appear
i have tried a lot of reinstall and removals

ADB driver woes

New laptop (to me) Dell e7470.
Win7 x64
Phone: XT1575
Installed:
MotorolaDeviceManager_2.5.4
MotoHelper_2.1.32_Driver_5.4.0
Motorola_End_User_Driver_Installation_6.4.0_64bit
(also tried Kushik Dutta universal adb driver from 2013)
No adb driver detected or found when all the other drivers install fine when plugging in the phone
I've tried multiple usb cables, but this all works fine on my other computers.
If reboot to fastboot Motorola ADB driver is found and installed
But no adb driver when in rom
I've done this successfully for years, first android device many moons 2008ish
I dont know why this laptop is giving me troubles, or maybe i'm just gettin old and forgot a basic sequence or step to success.
Thanks for any ideas, its got to be something dumb.
You need to turn on usb debugging - developer options.
Minimal adb & fastboot installed too.
Dev.opt. - settings - infi about phone - tap few times compilation number. @eigerzoom
What for do you need adb if fastboot works?
MDM is all you need for drivers.
I have adb debugging enabled
I apparently need it for tethering, since that isn't working.
Works just fine on my other win7 asus laptop.
Any other ideas?
it feels like windows is missing something, but its hard to feel a computer
Run cmd and type:
adb devices
I've done that, thats how i test it.
its blank
actually i test it with 'adb usb' which gives error: no devices
File transfer works?
how would it transfer files if no device is found?
adb device shows up in device manager with an error
File transfer - mtp - not needed adb drivers. From notification bar you can change/enable when connected.
---------- Post added at 07:31 PM ---------- Previous post was at 07:28 PM ----------
Error in win dev manager - rpm - update driver - choose from installed.
Find & choose "adb device".
I'll test it soon, sorry
Also in developer settings you can choose usb configuration mode
if I cycle through them all
All drivers get recognized except in 'audio source' mode xt1575 no drivers install, and in 'rndis usb ethernet' no adb drivers install
I haven't Windows english version - I don't know names.
So I suggest:
Uninstall all Android programms(apps) & drivers from pc, restart pc.
Install and run MDM, when it finished connect Moto with debugging on, allow the connection on Moto(it should ask itself) .
Anyone else???

No try what @dzidexx suggested, before asking for someone else! Especially since his solution isn't hard to try out and see if it works!
I've done all that....obviously....
ANYONE ELSE ???
something tells me i have to install a stock rom to get the adb driver to install
and then it will work fine installing other roms after that
running LOS13 currently
i've run into this in the distant past on pre 2010 devices
anyone else with ideas?
