So far, it's worked fine here. The other team members are going to test
it out and let us know. I've dumped a couple of 100's of megs to the Rio
using usbdevfs and no problems, yet. :) I know that we plan to support
BOTH interfaces for compat with the xBSD folks, since they don't have this
capability... I just got the thing to work the day I posted the
comparisons, so I know that we'd like to hammer at it a little bit.
