[Vadi]

Thanks a bunch

Hi,
I just installed Ubuntu 8.10 64bit on my Dell Studio 1735.
I am trying to configure my finger print reader for authentication. I tried fprint, thinkfinger 0.3 etc..but i am not able to get it working .

When i did fprint_demo, it says "No Device Found"..
can anyone who have successfully configured it .. plz share your solution..
thanks,

Hi,
type:

sudo lsusb

and visit this pages: Unsupported devices and supported devices. And even more try to explore Fprint wiki.

With regards.

Thanks Moob,
This is what i get with sudo lsusb

Bus 007 Device 002: ID 05ca:18a1 Ricoh Co., Ltd

Bus 002 Device 003: ID 08ff:2810 AuthenTec, Inc.
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

My computer does have,
5 usb ports, 1 hdmiii, 1 vga and 1394 port...
i did see AuthenTec in unsupported page that u had..
its using AES 2810

i wonder if there is something I can do to make it work coz i did see in some other thread that people did have it working on their Dell Studio..
(perhaps diff driver?)

in vista, fingerprint works fine and it's called uptek touchstrip (so supported by fprint)..any solution?

I also receive a segmentation fault on my Samsung X360, the print device appears to be a "AuthenTec AES1610". Not sure if this helps, but this was found in dmesg:

So I think I found out why the segmentation faults were happening. My friend actually has the exact same computer (and print reader) as well as the same version of ubuntu, but he didn't experience any seg faults. Anyways the conclustion we came to was this:

When scanning a print, you absolutely have to swipe your finger across the reader. Place the bottom of your "print" at the top of the reader, and drag it across (top to bottom) until the top of your "print" passes over the reader. Think of it like a scanner that scans from one end of a page to the other.

The way I was getting the seg faults was just putting my finger on the reader and removing it. I have no idea why it seg faulted, but apparently using the print reader correctly fixed it . So all in all, everything is working fine for me now.
