There are already several supported USB external MIDI interfaces whose driver can be found here:
http://member.nifty.ne.jp/Breeze/softwares/unix/usbmidi-e.html I have read about this somewhere a while ago and then also posted it on this list wondering whether any of these worked well and whether anyone had problems with any of the supported devices and/or driver. Due to fact that I am yet to find out more about this one, I have no clue how well they work in comparison with the serial-port devices (but if the driver proves to be stable, my assumption is that it should be far better than the serial port counterpart).
