Yes, I bought a USB200M for $20 with the hopes of it working as a USB 1.x device for now and then suddenly getting faster once our 2.0 support is done. Bernd Walter (ticso@) is working on 2.0 support. > Of course, I don't actually have any of these pieces of hardware myself. > I guess I could stop by CompUSA on the way home tonight... > > Now look what you went and started. Hehe. CompUSA is full of tons of these things, all not supported. I gave up and spent the $40 for a USB100TX because I don't have time to work on the driver right now. I'll make you a deal: if you continue to work on the ethernet drivers, I'll work on some more CAM patches. :) Thanks, Nate
