If you were able to flash back to an original bin, any way I can gleen some instructions off of you? At this point my machine cant "see" the USB adapter at all, it gets installed as "Unknown Device" and as such when I try to install drivers for it any driver fails because they arent for "Unknown Device".
Further than that, I dont know if it is the correct Kawasaki chipset, but it was on Ebay (not the seller you mentioned) as a 3c460 rebadged (logically deducing the "a" because it was only 10 mbit).
The reason I think they didnt work out of the box is because the VID and PID are different than stock 3com stuff. Someone here said they have a different chipset, but one that works with Audrey.........they have instructions on how to get it to work here: http://delsarto.tripod.com/audrey/
