Having a related issue but suspect it may be hardware and a warranty matter but will hold off going into excessive detail until I know the discussion isn't dead.  A quick limerick, joke, made-up word, etc. just to confirm someone is monitoring.  Thanks.

Device Descriptor Request Failed

Had the same issue on my Dell XPS 9570, in device manager it said “Unknown USB Device (Device Descriptor Request Failed)”, I assumed that was the missing Fingerprint sensor.

Checked that I had latest bios and enabled Software Guard Extensions, but no success.

I then did then remember that when changing keyboard I had to disconnect the Fingerprint sensor.

Opened laptop, and correctly, my connector was not seated correctly, fixed it, and when booting up the fingerprint sensor showed up.

for the newcomers, check if the port you are is is a 3.0 or a 2.0 port. cause i tried using my old external drive and I accidentally connected it to the usb 3.0 but the drive didn't support it. When i connected it to usb 2.0 (usually on the left side) it worked normally.
