So I finally got around to building a new kernel today.
and after rebooting I get:
[ 131.832084] usb 2-1: new high speed USB device using ehci_hcd and address 3 [ 131.969795] usb 2-1: config 1 interface 3 altsetting 0 bulk endpoint 0x7 has invalid maxpacket 8 [ 131.969800] usb 2-1: config 1 interface 3 altsetting 0 bulk endpoint 0x87 has invalid maxpacket 8 [ 131.970886] usb 2-1: New USB device found, idVendor=0763, idProduct=2080 [ 131.970890] usb 2-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [ 131.970892] usb 2-1: Product: Fast Track Ultra [ 131.970894] usb 2-1: Manufacturer: M-Audio [ 132.060121] usbcore: registered new interface driver snd-usb-audio nevyn@cetacea:~$ amidi -l Dir Device Name IO hw:1,0,0 Fast Track Ultra MIDI 1
Which is excellent and solves my problem.
now to find and apply that mixer patch.
Grant.

Sorry, Clemens,
I must have messed around with too many Alsa versions on my machine, again. Your suggested fix _does_ fix the issue!
Would you mind adding this to the git tree? Or shall I prepare a patch?

Try replacing the comment with:
{ .iface = 3, .type = QUIRK_MIDI_STANDARD_INTERFACE },In the meantime I started a bisect session on the mainline kernel. The cause of this issue lies in the refactoring done last year. I couldn't identify the exact patch introducing the regression, though, since starting at step 10 the kernels would not boot. See the corresponding git bisect log (the last revision is the first one that would not boot).
