Any idea why it's happening and how to investigate it?
Validity Sensor (VFS301) USB\VID_138A&PID_0005&REV_0<90 Driver Version 22.214.171.124
IIRC it was based on a Windows 7 64bit driver because there doesn't appear to be a Windows 8 64 bit driver yet. At least one that worked. I checked a couple of weeks ago.
