I have an iMito MX1 with a RK3066 chip running 4.4.2. When I plug it into my computer, nothing happens. I don't see it anywhere in Device Manager (Windows 7 x64). It's not in "Other devices" or anything... it doesn't even show up as a device that can't be installed at all. It's as if I hadn't even plugged it in. Therefore, I can't use ADB.
I know the USB port is working fine because I can see the device when I boot in Recovery/Restore mode and I can successfully flash ROMs to it using the Rockchip BatchTool. I can also successfully use adb with my HTC One (m7) for example.
Any ideas?
Try a different USB cable?

I've tried two different cables and two different computers. Same outcome...
I've managed to connect with ADB through Wifi, but it still baffles me that the device isn't detected by windows!

I took the OTA to 4.3 on my Nexus 7. It was previously unlocked and rooted, but had no kernels, etc changed. After the update ran, I lost root as expected, however, in trying to get it back, I've discovered I'm having a couple of other issues.
First, the device is no longer working properly via USB on my PCs. On both my Win 7 and Win 8 PCs, the device won't properly connect to where I can browse files or anything else. On the Win 8 computer, I see a Nexus 7 device in Device manager, but drivers won't install. I downloaded the drivers from the Asus site, but trying to manually install them doesn't work on the Win 7 machine, and on the Win 8 machine, they install but don't seem to be working with the Nexus 7 as it still shows a problem in Device Manager.
The tablet also will not boot into recovery mode. I can power it up into fastboot mode, but if I select "Recovery Mode" and hit the power button, I just got the Android with the red triangle for a few minutes before it boots back into the OS. After doing some searching, I saw where you might need to have it plugged into a PC to get it to go into recovery, but that doesn't work, either (might be tied to the USB problem).
Ideas?
Did you turn on developer options, and USB debugging? Have you tried USB connection type PTP instead of MTP?
If you have the stock recovery, the red triangle and Android are normal. You can bring up a blue options menu by pressing the power and volume up buttons from the red triangle Android.

Yes.
Try another driver source. Wugfresh's installation is a lot tougher than Skipsoft's, but try the other guy 's system.

I was using the stock drivers off the Asus page. I'll look around for the two you mention. I assume they're posted on here somewhere.
And about the recovery just try flashing another recovery from fastboot

Without USB access? That's my dilemma.
OK, I'm getting closer. I got TWRP installed and rerooted it. I had to do the "Revoke USB debugging authorizations" on the Dev Options screen. Then it would work via ADB.
Still not browsing files yet on my desktop, but at least I know I'm talking to it. So now I'll play with the driver installation a bit.
EDIT: Well, drivers reinstalled for about the 4th time, and it's still not allowing me to browse files from my desktop. Galaxy S4 works fine as soon as I plug it in, even if I also uninstall it's drivers. Ideas? I obviously have it working over USB because I can give it commands and reboot it via the PC.
OK, try this one. Plug in your tablet to pc, go to hardware manager, find your Android Device then choose Uninstall (choose Remove all drivers for this device), unplug and plug in your tablet again. Your Windows should discover few new devices (mine has discovered three) and download drivers for them then you should see Android ADB Interface in Android Devices and Nexus 7 in Mobile Devices.
--edit--
I've solved my issue

After you plug your nexus in have you unlocked the screen to see if it is asking you to authorize the tablet?
What other steps have you taken? Have you installed proper drivers? Have you manually chosen to update drivers with the sdk drivers if in device manager is showing the nexus? Have you tried the drivers from Asus?

I personally did all of those things. After having the Nexus "forget" all the other PC authorizations on the dev screen, I finally got it to accept ADB commands, just not to properly install drivers that would allow me to browse files like it had done on 4.2.

Nexus doesn`t appears in device manager. At all. It starts to charage, but no reaction in device manager, no any reaction(except charging) at nexus. On computer it looks like i didn`t connect anything. I`ve trying to intall drivers as legasy hardware, but nothing changes. Sorry for my english.

Try turning off usb debugging. My tablet cannot connect to pc but with usb debugging off it at least recognises tablet as a media device and this enables me to view its files
.but still the problem of not being able to root
Hey,
So I got my D802 today and I want to do the whole Root, Recovery, ROM shenanigans.
But for the love of god I cant connect the phone in MTP mode, so I cant Root, nor install a recovery.
I cant connect to the LG PC Suite either.
Any Ideas?
what connection type are u choosing after plugging it into the computer? are u running Windows, Mac, Linux? Windows will work with mtp out of the box but I think Mac and Linux need phone drivers installed. Windows will need drivers when you're ready to "unlock" using adb.

when you first plug in your phone it gives you the option to install the drivers needed to connect in the different modes, if not on the top right corner of the menu with charge/mtp/pc software it should have the option to install the drivers

you never said what connection type you're choosing on the phone after plugging it in. there are a few options and change how the phone is seen by Windows. some options won't have it display as an mtp device or as a drive letter in my computer.

Really Weird
I'm having the same issue. I'm running OptimusG3 v1.3, I've never had an issue with it before, I used MTP to transfer files yesterday, worked flawlessy, now it won't. I was trying to map the G2 as a network drive, I installed LGPCSuite, a couple of other software that should be inconsequential, and suddenly my phone says connected as MTP, but my laptop won't recognize or show the device in My Computer. I get installing device drivers prompts, I used the hardware and devices troubleshooter which told me 'LGE Android MTP Device has a driver problem' and LGE Mobile USB Modem has a driver problem. Reinstall device driver -> completed, but still not fixed. I installed LG's universal uSB tool or whatever, no fix. I have no idea wth is up (It's not a USB debugging accidental toggle either). I'll try uninstalling PCSuite. I though it would be more useful
... and is no longer recognized when connected to a computer via USB, meaning I can't return to stock to get ready for the Lollipop OTA.
Got a rooted Nexus 4 running the latest PA beta.
What happens when connecting to PC:
- On two different Windows machines: systray popup saying "USB device not recognized. The last USB device you connected to this computer malfunctioned etc.". In device manager it says "Unknown USB device (device descriptor request failed)"
- On elementary OS, based on Ubuntu 12.04: nothing, besides charging.
No USB debugging connection notification on the Nexus 4 either when plugging in.
What I've tried (USB debugging enabled, all relevant drivers installed):
- Settings > Storage > USB computer connection > check Camera PTP (used to be required in order to get an RSA key prompt when connecting to a computer, now it does nothing)
- Flashing latest stable CM to see if PA was to blame. Made no difference.
- Uninstalling device through device manager in Windows and reconnecting. No effect. Driver update doesn't work either, finds nothing.
- Using Wugfresh's Nexus toolkit to see if that worked, but that obviously doesn't work either when the device isn't recognized, same with the Universal Nexus Linux Toolkit on Linux.
- Scouring the net for solutions and coming up with nothing
I have flashed factory images before on this phone without problems. Should I consider it a hardware failure by now, or is this a known issue with a fix?
Try a new wire, different usb port on computer, finally look into cleaning your charging port on the phone/replacing it.

Tried three different cables, every port on two laptops, no joy - my girlfriend's phone connects normally.
Wouldn't replace the charging port, then I'd just get a new phone since it's a 2 years old Nexus 4. If only there was a way to flash the factory image using only TWRP.

Thanks jd1639, that seemed to be exactly what I was looking for -
- but then I had an extremely blonde moment and formatted everything in TWRP, wiping the ROM I was gonna flash in the process, on a device where USB file transfer doesn't work anymore
My phone is now a paper weight.
Have you tried the file manager in twrp yet? I've found it connects when nothing else will...
Ive been searching and trying for quite some time now for a solution but I have yet to find one.
My problem is this, I've soft bricked my Nexus 7. I can get into fastboot and recovery (CWM).
My computer has had a fresh install since i rooted last, now when i connect with USB it doesnt even come up in device manager. Everything ive found online tells me Windows will automatically detect the device then i can update the driver. But i cant even get that far!
I was wondering if anyone could PLEASE help me figure this one out? Is there some way to force Windows 7 to install a USB driver for Nexus 7. Ive downloaded the specific driver.
I'd hate for my Nexus 7 to end its life this way.
Did you try with wugs toolkit. It should have multiple solutions for USB drivers.

I tried Wugs toolkit... also step by step, manually in SDK but Im always getting stuck at "Windows will automatically detect your device" because it doesnt.
the only solution i can think of is to get another nexus 7 to install the drivers and take it from there, but thats a leap i'd rather not take unless it's completely necessary. Even then there is no guarantee that it will work.
Are the latest chip set drivers for the computer installed correctly? All windows updates and drivers? Tried another USB device, cord, and port? Of the 5 ports on my laptop only 1 works for adb and fastboot.

When using WUG's Toolkit be sure to use the USB deview tool inside the driver section.. Remove all of the entries with the Vendor IDs listed in the tool dialogs.

Interesting that some of you have been able to get adb working. I've tried every possible USB drivers and cannot get adb working for my nexus 7, nexus 10, or Acer iconia A1-830. My phone still runs android 4.2, connects no problem. There is no solution, must be because I'm still running winxp on laptop
Nexus 6p 128gb, latest PN7.1 rom, carrier is project Fi. Working fine as is but I'd like to try out 8.1. Plus, I can never get file transfer mode to work, irregardless of what does or does not install below.
I can't get the drivers working properly on my windows 7 pc. On two different machines.
What I've tried...
A. First uninstalling any /all android drivers via device manager as many guides suggest.
B. Plugging in with debugging off. Drivers installed but not adb.
C. Plugging in with debugging on, all drivers fail to install.
D. Installing via the sdk. Still tries to install the drivers and fails when I plug the phone in.
E. Installing the drivers via the Google provided USB drivers file. YES the authentic ones. Windows won't even recognize those. When I point the drivers installer to the folder where I unzipped them, it just says it can't find any drivers.
Is there any chance I could have jacked something up in the phone whilst screwing around with twrp, xposed, Magisk, etc in the past? Maybe a bad vendor image or something? Please help. This is making me insane.

Try a different Usb cabel sounds like the one your using is faulty.
Problem somewhat solved. It wasn't the cable. Something was screwed up in the works. I did a factory reset and got it to work on one of the two PC's I was working with. After that I was able to identify the phone with fastboot and do what I needed.
I forgot to include the fact that I was working with multiple cables because I had the same thought. I was using
1. Inatek 3.1 Gen2 cable
2. HI-CABLE
3. That stock little 8 inch cable that came with the phone.
