I have the same issue with my UA25 on a Raspberry Pi. With advanced mode
enabled the UA25 simply doesn't work well on the RPi. JACK does start
but a lot of xruns are generated. My guess is that this is probably due
to the poor USB implementation of the RPi. The workaround I use is
adding an extra USB-MIDI cable.
