FPR with thinkfinger won't work on OpenSuse 10.2, T60p

[Troels]

Hello,

I have a fine running install of OpenSuse 10.2 on a T60p 2623-DDU.
I have tried to get the fingerprint reader working, but i just can't. The FPR works upon bootup and in windows, so i know it isn't faulty.

I have followed this guide: http://en.opensuse.org/User:Fseidel/ver ... nger_howto

And installed the latest thinkfinger from sourceforge ( http://thinkfinger.sourceforge.net ), latest version 0.3. Did a ./configure and a make install. It installed fine.

However, when i, as root, do a tf-tool --acquire it lets me swipe my finger three times as expected, and it does detect that i swipe my finger, and rarely there's any mismatch. All fine.
After the third swipe it says

Code: Select all

Storing data (/tmp/test.bir)...

After 20 seconds or so i'm greeted with this:

Code: Select all

Warning: usb_bulk_read expected to read 0x40 (read 0x28 bytes).

The hex byte size read is pretty random, but it is never 0x40 - always lower.

Can anyone help me on some troubleshooting?

I have the same exact problem on my T61p. You have to give a few trys and eventually it will work. I didn't have much time to debug the code, but it looks like either the Thinkfinger code and/or the libusb drivers are buggy. Once you're able to actually create a name.bir file, everything should work fine again.

Thanks for taking the time to register here and your reply
I will make sure i have the latest version of libusb, although i haven't seen it updated for a couple of months now.
I'll try again.

I had the same problem recently.

Now I got it up again by installing libusb++-0.1-4c2 in addition to libusb-0.1-4 on my Debian sid system.

Hey, you're like, right next to me.

It turned out for me too - patience was the key.

But regardless of it being 10.2 or 10.3 opensuse, there's a large bug which prevents finger print readers from being used for login.
Even if you don't use it, it will crash if the fingerprint reader is initialized correctly upon startup when modules are loaded.
The best way is just to uninstall everything related to the FPR (thinkfinger, pam-thinkfinger).
I know this sucks, but lately i'm getting really FED UP with KDE dev./supporters replies to different issues - which they do not think is an issue.

The motto seems to be that if it hurts poking your eye with your finger, then stop doing it.
This is the same reason why you can't disable scrolling in the KDE taskbar, which can be a nightmare with touchpads since it is easy to scroll by accident.

In Suse 10.3 the login on the main screen works, with the inbuilt thinkfinger program.
It stores the files in /etc/pam_thinkfinger , and su command at a terminal lets me swipe fingerprint.


i tried to compile as listed in wiki, everything went sucessful, however common-auth seems to be not picking up the complied bioapi pam modules and there is no fingerprint prompt at the main login screen.

Does OpenSuse have a newer kernel you can try? If so, maybe try it and building the modules from source again.

2 cents, I installed thinkfinger on 2.6.18 and 2.6.21 - .24 fine on Debian and x61s, though tecognition/PAM seems more buggy for root than sudo for some reason. Fingerprint always prompts and works for XDM login. My only issues were sshd and PAM conflicted and unloading uhci_hcd to save power disables the FPR.

anyone work out problem with

rssb,
Interesting! So you are never thrown back from X to the terminal/console mode when using the FPR?
What programs/modules are installed to make the FPR work for you?
I'm thinking there may be two instances or two modules counter-acting each other perhaps...

Lightweight,
Hmm, not currently - latest is 2.6.22-18 if memory serves me right.


Reaper,
Just be patient. I know it is very irritating, but keep repeating the process many times and it will suddenly work.
Why the software suffers from this error i'm not sure why it does it.

[rssb]

Right now I am using the native package which comes with Suse 10.3 and it doesnot throw me back to a shell or console. I am in the full X environment (i am using KDE)

I will pm you the exact modules in use
