I recently loaded Windows 7 Pro on my Toshiba Tecra M5, equipped with a fingerprint reader. I downloaded the appropriate update drivers from the Toshiba website, but can't get the software to find the reader. I've gone through all the diagnostics and 'usual' remedies to no availability. The biometric log-on is one of the best features of the Tecra and I really want to get it working. Any suggestions?
