I use a Tascam US-122 on various Linux/PPC machines, and I've had this
happen before.  I wish I could say exactly what it is, but I'm pretty
sure it's a software misconfiguration.  I think each time, it must have
been caused by upgrades I did, but I never paid sufficiently close
attention, alas.  Check whether you have the usb-midi kernel module
loaded (in addition to all the usx2y stuff), et cetera.

Hope this helps.
