Fingerprint reader stopped working all the sudden

Hi all,

 

I was using the fingerprint reader on my ThinkPad T440 to sign into my laptop using Windows Hello without any issues when all of the sudden it just stopped working. I checked device manager and it shows it as "Unknown USB Device (Device Descriptor Request failed)", the full error is this:

 

Windows has stopped this device because it has reported problems. (Code 43)

A request for the USB device descriptor failed.

 

I tried installing the most recent driver from the Lenovo website - Validity Comon Driver version 4.5.507 - but there was no change even after a restart.

 

Then after doing a bit of research I tried installing the older driver - Lenovo Fingerprint Manager 4.5.122 - but that didn't work either even though the install was successful.

 

Does anyone have any suggestions on how to revive the fingerprint reader or is it toast?

Re: Fingerprint reader stopped working all the sudden

This can be closed, after about a week of not working it all the sudden started working again out of nowhere, makes me think it's most likely a loose hardware connection somewhere since I carry the laptop home in a backpack everyday.
