Rootkits and malware that hide in the partition table or uefi or msr will survive format and reinstall. Thanks to all those who helped for your time & support. I still don't know what caused the error 31, & which particular update fixed the conflict, was it dell support software which was continuously on or windows, but I'm pretty sure its fixed. I believe the miracle was due to the windows update most probably, just for reference I was on windows 10v.1909 before and even now, the update was minor a fix perhaps. I have now upgraded my bios and the sensor still appears to work. I enabled Microphone for a skype call and just out of the blue the sensor error code 31 which I was checking for frequently, just disappeared.
Then my antivirus software also found a simple malware, which shouldn't likely have any effect.
#Something went wrong windows 10 usb tool drivers#
I then restarted the computer, the sensor was detected and appropriate drivers were automatically installed, didn't check for error at this time. Then I downgraded the bios using Dells Bios Tool, Meanwhile Microsoft or maybe Dell launched an un-logged/unscheduled automatic update and perhaps a possible patch for windows, I don't know if they did it or if it was windows on its own because it wasn't logged. Then I uninstalled the sensor driver software and it was no longer detected aswell.
I don't know what fixed it but I'll go on chronologically.įirst I downloaded a utility named UsbSafelyRemove and using this I stopped the power to the fingerprint sensor virtually without having to disconnect it, this removed it from devicemanager by preventing it from getting detected for current session. I did a couple of things with a guy from nearest dell partner who provided me free technical support at their center, He guided me a little and I did a few things on my own. Just wanted to update it got fixed, without re-intalling windows.
