Finger Printing Scanner after Windows Upgradation

I am using Fingerprint Scanner which is not working after Windows 7 upgraded. i have installed the driver for the same but that also does not work for me. Whenever i am log in the Windows 7 it shows that can't find a fingerprint reader. I am using Toshiba Satellite U205-S5034, if any one having the solution for the same then help me with the same. Thank you.
