Hi,
Tablet: RK 3126
Manufacturer: Rockchip Fuzhou
Tablet OS: Android 4.4
Laptop OS: Win 10 x64
Problem: Not able to install drivers/ successfully connect the tablet to my laptop.
The tablet doesn't have a normal micro USB port, instead it has a 5 pin connector. Something like this. I cut a USB cord in half and managed to connect the tablet to the laptop. Now device manager shows "Unknown USB Device (Device Descriptor Request Failed)" which as I understand is supposed to happen with Rockchip tablets. Now, I cannot get further to this. I downloaded Rockchip driver assistant v4.3 and tried all variants of x64, x32 and win8, win7, vista, xp but nothing seems to work.
Please help if you have ever worked with Rockchip devices with Windows 10.
Thanks.
Turns out the USB cable was defective. What are the odds of that! Works great now

i have a windows 8 and my PC cannot detect my phone at all. when i connect my usb cable to my PC it charges it but nothing else. ive tried both the htc and samsung usb cable. the phone detects fine on my older PC. i'm not really sure on what im supposed to do now.
Try installing the Windows 7 drivers from here http://developer.android.com/tools/extras/oem-usb.html
I know you‘re on Windows 8 but I think the drivers should work fine
hi
i have buy lenovo ethernet adapter for my surface rt, but i connot found arm drivers
thinkpad usb 3.0 ehernet adapter
is it possible work whit my surface??
If you plug it in and it doesn't work automatically, then probably not.
I don't know if you're running RT 8.0 or 8.1. On 8.0 there was exactly 1 driver available for worked with USB adapters that used the AX88772 chip, but I'm fairly sure they are USB 2.0. This driver was NOT included with the OS.
With 8.1 I believe there are two drivers that shipped with the OS, but I recall reading that they don't automatically install when a USB Ethernet adapter is plugged in, so you might try running the add new hardware wizard and select the driver manually. I still suspect these drivers are for USB 2.0 but I'm not sure. Perhaps you'll get lucky...
Try install this driver. Only for Win8.0.
Finally caught the driver bug! W10 x64. Take one PC that would concurrently connect N10(Omnirom 6), N9 (rooted) and stock N5 and connect a Pixel C. Connects as a Pixel C in Device Manager under "Portable Devices" - enable USB debugging and W10 says "The last USB device you connected to this computer malfunctioned and Windows doesn't recognise it". Could write a book on the steps taken. Tried to add "Android Composite ADB Interface" via install legacy hardware and pointing to Googles USB drivers (v11) I get a no x64 compatible files error. Even cleaned out W10 driver store of relevant drivers via the command prompt ( and then discovered RAPR windows front end to pnputils.exe at https://driverstoreexplorer.codeplex.com/). Nexu5 with USB debugging + MTP connects perfectly haven't tried N9 or N10.
Any bright ideas?
Don't think this has any relevance with MTP working - Using Anker USB-C to USB3 cable with rounded edges on connectors - AFAIK this version has the correct resistor
download a copy of USBDeview for x64
open it, sort the list on vendorid
uninstall every driver with vendorid of 18d1
close the program, unplug all USB devices, reboot
make sure you have the newest google drivers on the pc
plug in pixel c and let drivers install, unplug pixel c and reboot
it should now work correctly
this routine has helped me every time i had issues with the pixel c and pc recognition
most of the steps came from wugfresh's nexus root toolkit advice on how to get proper drivers
i think what happens is drivers from other devices combine to create a situation windows can not fix so need to start over.
each device plugged in will get the install routine.
Hi,
I have a Lumia 950 phone running windows 10 mobile. and am intending to use a FTDI usb to serial(rs232) cable with the USB OTG port on the phone. however, the cable driver is not automatically installed. I downloaded an ARM-based winRT driver from FTDI but have no way to load the inf file to the phone.
Does someone did similar things before? help is much appreciated!
How to fix the error: The USB device is not recognized. Google Nexus 7 2013 Wi-Fi Tablet. Windows 8
Have you checked the USB drivers on windows
You should update them just in case
Why would you still be running Windows 8? Try upgrading to Windows 10 and see if that solves your problem. You can probably still get the upgrade to install for free.
