You might have hit a bug here that I introduced during a refactoring of the driver. Unfortunately, I can't reproduce that with any of the multiple USB audio devices I have at hand, but someone from the alsa-user ML offered me to send over his device that also show this problem, so I can have a look. Stay tuned please, and my apologies for the trouble.
Meanwhile, you could check whether any of the kernels between 2.6.39 -> 3.4 works for you - they all have the quirk for the JS-8.
If it's any help, I'm running Linux Mint 13 with a 3.2.0-34 kernel and it's working for me. I do get the following in dmesg:
[47696.764621] usb 1-6.2: new high-speed USB device number 12 using ehci_hcd [47696.858892] MIDIStreaming interface descriptor not found [47696.859099] init_device failed: MIDI 4-0: seq-midi
This is due to an error in the original quirk I submitted which was brought to light when some changes were made to the USB driver. I will try to tidy it up sometime.
Cheers,
