Fingerprint reader - ID 147e:2020 Upek - Thinkpad T430

I'm having some problems with fingerprint reader on Thinkpad T430 ID 147e:2020 Upek

For few days i was trying every tip i could find but it didn't work for me.

Mainly i tried to Build and make it running through Fingerprint GUI and i was able to build it and install it properly (after few fixes) but it simply was not able to pick up my device.

At one point i thought that i have solution, since i realized that Fingerprint sensor on this laptop is quite new and is maybe not supported by default with proprietary libbsapi.so so i tried to follow tips from this blog: http://volker.de/2012/12/fingerprint-gui-und-das-thinkpad-t430s/ Guy has exactly same device and in same PC but as i expected it didn't work for me.

Platform is Debian-squeeze

If you have any idea what could be solution, pls help.

You'll need to apply this patch to libfprint.

Used the same info as you did, but a quick look at the French Ubuntu doc did the fix for me: the problem appears to be that the fingerprint-gui doesn't have access to the USB device bus, thus, we have to give it to it.

Find your device's bus and device adress using the lsusb command, for me, it was:

Bus 001 Device 003: ID 147e:2020 Upek

Thus the bus is 001 and the device is 003. Let's call them x and y. Then, we use chmod (apparently it doesn't pose any security threat as the system fixes it by itself):

sudo chmod 666 /dev/bus/usb/00x/00y

For me, for instance, it was: sudo chmod 666 /dev/bus/usb/001/003

Then, follow the instructions given to you by the German guy (volker - the link you cited). On my side, I was running Ubuntu 12.04 (debian bro'), so I could use the fingerprint PPA. I don't know if Ubuntu PPA's work on debian. I suggest you keep your own install of the fingerprint-gui program, as well as the fix provided by volker's blog post. Then, just launch fingerprint-gui and it should recognize you device.

The German blog got actually updated was a problem with the quotes:

For non german users: Be aware to use the copy and paste funktion to insert the above lines in your 40-libbsapi.rules, because the quotes are different from that quotes that you get when hitting on your keyboard. It was pain in the a….. to find it out.
