driver problem


I recently upgraded my Shield Tablet to android 5.1, but I am unable to connect it to PC since then. I tried driver update through TADP Component Manager unsuccessfully. Manual driver update failed too, windows say I have that driver already. I have yellow triangle in Device Manager on that device.

Thanks for answer.


Please install the USB Driver manually using the C:\NVPACK\Drivers\How_to_install_driver.pdf.
Any more problem please let me know.

Best Wishes

That’s what I tried. Result is “Windows has determined that the driver software for your device is up to date”, but strange is also name of device “Unknown USB Device (Configuration Descriptor Request Failed)”

Did you deactivate you driver signiture using modifying startup setting in windows?naked drivers don’t work anymore after the update!windows ten should auto load your adb ,bootloader and USB drivers,???update pc
