[Thinkfinger-devel] Dell Latitude D620 - biometric issue

Hello,

I just got such a laptop yesterday, and have trouble trying to setup
the biometric chip.
Everything else is working fine (sound, keys, wifi,hibernation,...)
The BIOS version is A08 (04/03/2007)

The system is an Ubuntu Feisty x86. All the needed (verbose) info are
appended below.

What have I missed? Any hint appreciated.

1) I've installed thinkfinger 3.0, without previously running the
proprietary UPEK software.
2) uinput is loaded, and /dev/input/uinput is present (660)
3) launching "tf-tool --acquire --verbose" fails:

ThinkFinger 0.3 (http://thinkfinger.sourceforge.net/)

Running in verbose mode.

* Mode: acquire
* Biometric identification record file: '/tmp/test.bir'

Initializing...USB device not found.

4) lsusb doesn't show the device

the "Driver=(none)" seems strange to me, but I'm fairly new to the

6) it seems the device is continuously changing from address:

Hi Jordan,

Thanks a lot for your answer.

But, the base problem is that I don't see the device (points 4, 5 and
6 of my original mail).
I've not yet had time to investigate more, but I suspect that
something on the same bus might interfere. Thus, disabling the
smartcard reader and / or the bluetooth adapter might help.

Does someone at Dell have made the D620's one working on Linux?

Update: here are some more traces of the problem:

The "O2 Micro, Inc." devices seems to be the origin. But I don't know

This is for thinkpad, but Dell uses the same device.

Just a small update:
calling repetitively tf-tool -{acquire,verify} works 1 time on 2. This
is also true for lsusb.
not reliable enough for production, but it confirms the hub reset
problem, and the fact that the device is sometime (not for long)
reachable.

IIRC, I've disabled the smart card reader in the bios, along with bluetooth.
Still no tip on what can cause this reset?

For the recall:
- system is Ubuntu Feisty
- kernel is 2.6.20-15-generic smp
- libusb is 0.1.12-2
- Latitude D620 with A08 BIOS (the latest)

Hi Jordan,
Thanks a lot for your answer.
But, the base problem is that I don't see the device (points 4, 5 and
6 of my original mail).
I've not yet had time to investigate more, but I suspect that
something on the same bus might interfere. Thus, disabling the
smartcard reader and / or the bluetooth adapter might help.
Does someone at Dell have made the D620's one working on Linux?

Errno 71 is EPROTO (Protocol error)
The "O2 Micro, Inc." devices seems to be the origin. But I don't know
yet how to disable these.
