i am having weird problem on windows 10. i fresh installed today and was installing drivers and other softwares. i couldnt set fingerprint because it says biometric device is not enabled. then i realized this error code : 43 . i dont know if it s related with fingerprint or not. also i installed old driver of integrated webcam in compatible mode win 7. i dont know if it caused this problem either.
any help please?

it was Fingerprint. fingerprint socket was unplugged. after i re-plugged the socket windows recognized biometric device. then i installed thinkpad fingerprint driver 6.0, all worked fine. there is no unknown usb device anymore.

I had the same issue with a brand new Yoga 520-14IKB - in the Device Manager there was just 'Unknown USB Device (Descriptor Request Failed)'. It turned out I had to dissassemble laptop, unscrew the battery and under it there was a cable marked 'FP' (as in FingerPrint). After I carefully replugged the cable and put plactic holders in place (and assembled everything back together), Windows recognized Biometric Device and installed Synaptics WBDI driver.
I spent a few days, before I figured out that this 'Unknown USB Device' must be a Fingerprint Reader and your post helped me to try my luck with dissasembling the laptop and re-plugging the FP cable, so thanks for your help! It works fine now : )
