sorry, your patch looks still a bit hacky, perhaps because you wanted
to keep the usb-midi code as original as possible.

i think we need rather rewrite the top of usb device management (on
alsa).  there is also another problem in this regard, for example,
a device with both midi and audio is assigned to two different cards,
since midi and audio handles it individually.

let's discuss about it at first.

(BTW, could you check the legal condition of firmware on tascam
 device?  i'd like to put the stuffs but without this permission it's
 of course unacceptable...)
