This question is better asked on debian-user, however your problem is that
none of your drivers are recognising this device as being one that they
support.
Try Googling for the vendor and product IDs for your device (determined from
the output of "lsusb") and see if you can get an indication of the chipset,
and what driver supports it the chipset. Often the solution is to add the
vendor and product ID to the driver and rebuild it.
I've had USB ethernet adapters that were based on the Pegasus chipset, but
not recognised by the pegasus driver that have suffered from this problem in
the past.
