can't comunicate with fingerprint reader.

# cd thinkfinger-0.2.2
# unset CFLAGS
# ./configure --enable-pam --with-securedir=/lib/security

This appears to be the same problem I have with my R52 running Ubuntu
Edgy (Same error message atleast). I have tried some basic
troubleshooting with no success so far.


To let you know what I have tried so far -

My vendor and product ID match the source code and the reader works in
windows and also with the closed source driver.

My next step was going to be to boot into windows and see about getting
a dump of the usb traffic when using the scanner.

Thanks,
-Chris

Hi Chris,

Edgy (Same error message atleast). I have tried some basic
troubleshooting with no success so far.

The error message is always the same once the communication with the
fingerprint reader failed. That, however, does not imply that it is the
same error. Maybe I'll find a way to be more verbose on the cause. No
promises, though.

Thanks,

Timo

I *think* we have a T43 equipped with a fingerprint. I'll investigate.

Thanks for the report.

Thanks for the report.

I put some printf's on code, and see the error occours on
libthinkfinger.c, line 341 (_libthinkfinger_parse() routine).

The routine interprets "inbuf[6] == 0x07" as TF_STATE_COMM_FAILED...

If I can help you on tests, I'm ready

Actually, we do have a T43. But that T43 just works fine. I have no
idea why things do not work on a T43p. I'll keep you posted whenever I
get my hands on a T43p.
