I tried it and is perfect for the purpose to connect arduino to fluidsynth. Returning to the problem..., I imagine something like plugging arduino and appearing automatically in aconnect. Maybe the solution is to hack the FTDI driver. FTDI is the chipset that converts serial to USB, and needs an FTDI driver to create a virtual COM port: /dev/ttyUSB0. The solution could be hacking the FTDI driver with the ALSA libraries driver and making it an ALSA sequencer port. Joan Q
