actually i lost this function of validity finger print sensor a week ago when i was trying to fully recover the notebook from hp recovery manager by pressing f11 . then after its fully recovered i found out that i lost it .but before that its working perfectly . i always found an unknown device stuff in category of USB serial bus controller in device manager , even though its being considered as newly recovered notebook without yet attaching any USB device to notebook .then i thought if i full clean reinstall windows on my notebook , this issue will be solved but still not in progress, not working finger print sensor and still i found an unknown device in device manager .,as i already know where to download its
drivers but before i download hp protect tools with finger print sensor drivers , DOn't you think that there should be any biometric category in device manager before i download any
driver and tools related to finger print sensor ?
