I looked through the 1.0.24.2 code and couldn't find any mention of the
UM-ONE or it's product ID. Not a surprise considering this came out
only a few days ago.

That appears as a pretty normal MIDI interface.
The UM-ONE however, does not seem to be following the same rules:

Obviously, alsa will not be able to detect this as a generic USB midi
interface. Roland seems to have ignored the USB standard and set the
bInterfaceClass to a non standard value (Should be 0x01). Is this doom
for alsa and the UM-ONE then?
