I have a problem with the login process for Windows. A while ago (nearly a year now) I installed a USB fingerprint reader and this worked fine for a while when all of a sudden it appeared to stop working on the login page. It turns out that if I scan my fingerprint within the first 2 seconds of the login page appearing then Windows recognizes the device and allows me to log in using biometrics, if I try after the 2 seconds then it doesn't work and I have to use a password. I really don't understand, the device is recognized, working properly and even if it doesn't work for logging in then I can still access biometric settings and everything as if it was completely fine.
I'm presuming that this is a driver conflict somewhere that during the loading process something happens after 2 seconds that prevents the fingerprint reader from operating correctly but how do I find out what?!?!?!
