[fprint] Adding support for unsupported TouchStrip device.

[Juan Jesús García de Soria Lucena]

Hi everybody.

I've purchased a new laptop recently. It's an Acer Aspire 6530G with
an integrated UPEK TouchStrip sensor that seems to be unsupported by
libfprint (USB Id 147e:1000).

I'd like to help adding support for this device. I've already written
a LIRC driver for the IR receiver integrated in that laptop, so I
think I'm technically capable to write a libfprint driver too, but I'd
like to have a little bit of help to begin with it.

I can get USB captures from the device in Windows Vista. Who should I
send them to, in order to identify which kind of device it is (imaging
device only, I'd bet), and which is the best existing driver to use as
a starting point?

I attach the lsusb -v of the device at the end of the message.


Best regards,

   Juan Jesus.
