Thats too bad, but not really entirely hard to believe. The I/O rates are 
pretty high and probably timing is moderately critical with USB. Ethernet is 
easy because you can always tolerate delays in sending packets, not so with 
other devices. I expect 115.2k serial might be a bit iffy as well...

Webcams are pretty darn well supported in Linux though. I just got a Sony 
Cyber-shot DSC-P1 the other day. I guess you wouldn't quite call that a 
"webcam" but it works great with Linux USB! You may well find you can simply 
do your capturing in Linux.
