It should not, but my bet is it does currently because this device has
both an MIDI streaming interface *and* an HID one for those extra DAW
control knobs and buttons on the device.
Which means probably that both usb_hid and usb_midi kernel drivers are
accessing the device concurrently.
It should be possible, but maybe we don't support it well right now.
Please file a bug ticket for this issue, as it could be a deeper issue
than just USB MIDI support.
Read the builtin Welcome documentation "Tips for a helpful bug report"
page on how to collect as much as information on the crash and attach
it to a new bug report ticket.
Bye,
Philippe.
