The hotplugging code works, but for some reason, the driver isn't able to create the sound card object. I'd guess that the snd_cards_limit parameter is set to 1, so that ALSA refuses to use more than one sound card. (Maybe the SuSE installation sets this to 1 because it doesn't know about USB MIDI.) The following lines for /etc/modules.conf should work for your configuration: alias char-major-116 snd options snd snd_cards_limit=2 alias snd-card-0 snd-cmipci options snd-cmipci snd_index=0 alias snd-card-1 snd-usb-midi options snd-usb-midi snd_index=1 # (entries for OSS omitted, see my other mail) HTH Clemens ------------------------------------------------------- This sf.net email is sponsored by: OSDN - Tired of that same old cell phone?
