There is a kernel driver for this chipset; try
"modprobe ftdi_sio product=0xb8d8".  This will give you a serial port
which you can try to configure for the correct baud rate and see whether
MIDI bytes come out.  (There is currently no mechanism to make a MIDI
device from such a serial port; this would require extending or creating
a driver.)
