[PlanetCCRMA] More on Triton Extreme USB

[Jason Balicki]

Ok, I know I'm close here.

How does one go about adding a new USB device to Linux?

I'm pretty sure that if I can attach the snd-usb-audio
driver to my Triton that it would work, but I don't
know exactly *how* to go about doing that.

I *think* it has something to do with adding detection
information to /etc/hotplug somewhere, but I don't
know where to start.

The kernel log messages say:

Jun 29 21:31:42 daw kernel: usb.c: USB device 2 (vend/prod 0x944/0x10) is
not claimed by any active driver.

when I plug in the Triton.

And when I manually "modprobe usb-midi" (usb-midi is blacklisted in
/etc/hotplug/blacklist to prevent it interfering with the other
usb midi devices) I get:

Jun 29 17:30:57 daw kernel: hub.c: new USB device 00:07.3-1, assigned
address 26
Jun 29 17:30:57 daw kernel: usb-midi: Found MIDISTREAMING on dev 0944:0010,

Jun 29 17:30:57 daw kernel: usbmidi: /dev/midi01: in (ep:84 cid: 0 bufsiz:
0) out (ep:03 cid: 0 bufsiz:64)

So success!  Sort of...  It's claimed by usb-midi, and even
finds the ins and outs, but that's not ALSA!  (Interestingly,
it appears that I can have direct control over both the
Triton itself and its external MIDI IN and OUT ports.  Cool.)

I think I need to set it up so that "vend/prod 0x944/0x10" *is*
claimed by an active ALSA driver, namely snd-usb-midi, but I'm
not sure how to go about doing that...

Any help at all is appreciated, even if it's "go read this".
Again, I'm running FC1 with an up to date PlanetCCRMA on
top.

Thanks alot, and sorry for gumming up the mailing list...
