It is connected into a USB hub that has a number of other things connected to it (none in active use). >> I didn't get any xruns, and didn't see any messages from JACK about any >> problems. >> >> Using JACKDMP using alsa-midi (E-Mu XMidiPort 1x1 over USB 2 port and an >> external USB sound card hooked to a different USB port).
