Hello, I am trying to make my Edirol UM-1EX USB MIDI Interface working with Plan 9. usb/usbaudio is known to work successfully with Edirol UA-1X, which is a similar, but older interface.
The problem: usbaudio does not create /dev/audio and /dev/audioin files and crash when trying to access /dev/audioctl. Here is what I have tried: term% usb/usbd term% usb/usbaudio term% du -a /dev | grep audio 0 /dev/audioctl 0 /dev/audiostat term% ls /dev/audioctl 148.4 strlen(a->s) < 1024: assertion failed usbaudio 148: suicide: sys: trap: fault read addr=0x0 oc=0x00011804 ls: /dev/audioctl: i/o on hungup channel term% Do you have any idea to make Edirol UM-1EX working? Thank you. -- David du Colombier
