I am trying to get a Planet CCRMA linux box up and running with PD. I am having one problem. I cannot get UM-1 (USB MIDI) to show up as a MIDI input/output device in the MIDI Settings... window of PD (Media>MIDI settings...).
This MIDI device shows up as an Audio device instead. When I click on the Audio Settings (Media>Audio settings...) the UM-1 is in the audio list.
AFAIK, all usb devices (MIDI and audio) are being managed by one and the same alsa driver, namely snd-usb-audio. Assuming you use hotplug, snd-usb-audio is being loaded at fairly early stage, when usb is being configured. Hotplug simply detects a usb device and loads it even before you get to the sound/alsa loading rutines. One efficient way to prevent this is to blacklist snd-usb-audio and let the sound loading scripts take care of loading that driver.
As a test, try booting with your MIDI interface unplugged and se where that gets you. then see what happens when you plug it in.
