Device reported an error during verify: Response had wrong subcommand type
I have a very old fingerprint reader. I can enroll fingers, but use of the pam authenticate action causes the daemon to print:
Device reported an error during verify: Response had wrong subcommand type
The pam client then gets an immediate fail.
Device is: Bus 001 Device 006: ID 0483:2016 STMicroelectronics Fingerprint Reader
Let me know what further information I can provide to track this down. I have a debug self-build of fprintd
