The driver doesn't try to discover anything, it just blindly sends the initialization SysEx for one device. Do you have any documentation for these SysEx commands? > I tried to use the generic serial MIDI interface with the Mark I > connected thru properly detected Prolific USB -> serial adapter, but > it didn't work at all. The snd-serial-u16550 driver works only with chips compatible with the good ol' 16550, i.e., only with motherboard and most ISA/PCI card ports. > I tried to write a simple C program to check if the error is > on the Perl side, but it didn't work What exactly does "didn't work" mean? Use SND_SEQ_OPEN_DUPLEX in snd_seq_open. Drop the snd_seq_event_input_pending call; snd_seq_event_input automatically waits for new events.
