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.)
