MIDI works because it is done by another driver.

Follow these instructions to see if you can get the US122 MKII working 
like a US122L:
http://www.premiumorange.com/la-page-web-of-phil/index.php?page=P030101#conseils_installation

The interface is not hw:0 but usb_stream:1.

Also the US122L works with both ehci-hcd and uhci-hcd, the US144 only 
works with uhci-hcd.

Good luck, others tried it before and it didn't work.
