General USB troubleshooting:
Verify hardware
Connect the device to your PC using another USB cable, a different USB port, or connect the device to another PC. Try also other USB devices. This will tell if the problem is hardware.
(This part was already done.)
Uninstall the USB Drivers
Open Device Manager and expand category Universal Serial Bus Controllers, right-click on all "Unknown USB Device (Port Reset Failed)" and then click Uninstall to remove the device. Finally, restart the PC so Windows will reinstall the device automatically.
Update the Generic USB Hub Drivers
