now a new version is cvs.  it dumps the descriptor at
/proc/asound/cardX/descriptor.  if the cvs servers is not sync'ed,
please let me know.  i'll send you a patch.

btw, you might try another hub module.  for uhci there are two
modules, uhci and usb-uhci.  i'm not sure which one is better,
though.
