This device is 10 BaseT only right? Not 10/100?

a good try, but I don't think this device is based on the AMDtek pegasus
chipset. It is probably based on the KLSI chip, which needs a different
driver.

The vendor / product ID matches an entry in
http://www.linux-usb.org/usb.ids that is for a KLSI based device.

The entry in /proc/bus/usb/devices means that the standard requests to
get device information worked. A mouse would also have given you an
entry in /proc/bus/usb/devices, albeit with different information and
different endpoints, and you would get the same answer without the
pegasus module, since the pegasus module is not the right driver for
your hardware.

No, it creates an eth0 device when the device driver succeeds.

Bug introduced by slab poisoning? There were some patches that Georg
Acher has released that should fix this.

Yes, the 2202 10/100 converter works with pegasus.o

Small changes will not do. The KLSI device needs downloaded firmware.
However there is some code you could try that works for some people:
http://drivers.rd.ilan.net/kaweth/kaweth-0.2.tar.gz
You need to hack in your vendor and product ID.
more information on
http://drivers.rd.ilan.net/kaweth/

Buy a mouse or a keyboard, use the USB Guide
(http://linuxusbguide.sourceforge.net) and get some confidence that the
rest of the system works. Then try the ethernet.
Hope this helps
