Problem with E6500 fingerprint

I have recenltly bought a e6500 everything was fine till I tried to install windows vista 32 bit again . The boardcom USH w/touch sensor was not installed in my former OS and I didn't have boardcom TMP neither . But my fingerprint worked fine .
Then I reinstalled the windows and installed the latest drivers in order . I also updated the firmware but none of those helped me solve this problem .
When I try to enroll my finger print I get : "Device opened" and when I choose my thumb as an enrolling finger I get "an error occurred during enrollment please re-enroll"
Is there any thing that I can do ?
Best

 

I checked every step with a dell technician but he didn't find out how to solve this one .

 

I had the same exact issue. I can't recall how I fixed it but I think I had to uninstall and reinstall the drivers. I believe disabling the tpm in bios also helped. Sorry if I'm not much help, it was really late at night when I did it.

 

Thank you for your reply . But I tried to do so but it didn't work .

 

it seems u have to own and enable TPM before you can enroll any fingerprint.

and by the way, when updating the driver or the embassy trust suite, u have to disable the TPM first.
