Hello,
Long time since my reader worked with libfprint.
The attached patch workaround this.
I am getting:
upekts:error [__handle_incoming_msg] non-zero bytes in cmd response fb ff
While the expected is values are 0, 0. But these are not used afterwards.
Any clue what these bytes are for?
I got the following device:
Bus 004 Device 004: ID 0483:2016 SGS Thomson Microelectronics Fingerprint Reader
Regards,
Alon Bar-Lev.
