[9fans] usbaudio problem

[David du Colombier]

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.

Try 'usbaudio -d1' for more information, or' usbaudio -d-1' for very much
more information.

According to the USB configuration descriptors, this device
supports MIDI and nothing else.  Plan 9 usbaudio is for digital
audio input and output (A/D and D/A), not for MIDI.  Sorry.
