Hi Clemens (or others, if you can help),
I am trying to get my Edirol UM-880 to work with Rosegarden-4.0.9.7 and
alsa-1.0.4. This is a rackmount USB 8x8 MIDI interface. I have a
gentoo-2.6.5-r1 kernel with USB support compiled in.
------------------
/usr/src/linux # grep -i midi .config
CONFIG_SND_RAWMIDI=y
# CONFIG_SND_VIRMIDI is not set
CONFIG_USB_MIDI=y
------------------
The first thing I noticed is that it doesn't work with the default
Edirol driver, about which the manual says:
------------------
FPT technology will be used to perform high-speed MIDI transfer. We
recommend that you normally use this mode. FPT = Fast Processing
Technology of MIDI Transmission -- this optimizes MIDI data
processing by making efficient use of the USB bandwidth according to
the amount of MIDI data being transferred.
------------------
I get the following in /var/log/messages when I plug in a USB cable with
this driver enabled in the hardware:
------------------
usb 1-1: new full speed USB device using address 2
midi: probe of 1-1:1.0 failed with error -5
------------------
To change this, you have to follow the instructions in the manual to use
the generic driver mode. Ok, fine. I'm guessing Edirol isn't likely to
release specs for the fancy one, but I haven't gone about asking.
Now /var/log/messages shows me:
------------------

Which looks a lot more promising.
However, when I start rosegardensequencer, it doesn't show up:

------------------
I think I'm expecting to see another DUPLEX device, perhaps numbered
65,0. If I disconnect the USB cable, there is no change in the
rosegardensequencer messages. alsa-patch-bay doesn't show me the UM-880
either, and there is no change with or without the cable connected.
Finally, '/etc/init.d/alsasound restart' doesn't fix things.
So ... what am I missing here? I looked in various places but couldn't
find any information about what I need to do.
Cheers,
Chris

CONFIG_USB_MIDI is not the ALSA driver but the old OSS driver.
You want to use CONFIG_SND_USB_AUDIO instead.

Rosegarden doesn't support OSS devices. It will work when you use the
ALSA driver.
The first thing I noticed is that it doesn't work
with the default
Edirol driver, about which the manual says:
FPT technology [...]
The "FPT technology" is always used, regardless of the "generic
driver" setting. It's just a fancy name for the protocal that all USB
MIDI devices use.
To change this, you have to follow the instructions in
the manual to use
the generic driver mode.
The ALSA driver supports both driver modes.
Microsoft's USB Audio driver in operating systems before Windows XP
didn't support USB MIDI, and Bad Things(TM) would happen if this
driver was loaded for such a device. Therefore, USB MIDI devices must
pretend not to be an USB Audio device to prevent Microsoft's driver
from loading. This is the whole difference between the "Edirol" and
"generic" driver modes.
I'm guessing Edirol isn't likely to release
specs for the fancy
one, but I haven't gone about asking.
The USB MIDI specification was written by Roland.

Regardless of whether or not CONFIG_SND_USB_AUDIO is a module, I now
only get:

in /var/log/messages. 'modprobe snd-usb-audio vid=0x0582 pid=0x0015'
doesn't help the situation. 'amidi -l' only shows me my Crystal
SoundFusion card.
I also tried playing with CONFIG_SND_VIRMIDI, and if loaded /
compiled-in, it also shows up in 'amidi -l', but doesn't help the
snd-usb-audio situation (which is what I expected). It doesn't show up
in rosegardensequencer either, but I'm now using 'amidi -l' as the test
since it's faster.
However, lsusb -v gives me:

Talk about confusing/misleading advertising/literature! Thanks for the

I tried switching the UM-880 back to the FPT mode, and it works now. I
don't know if that's a regression, but in any case I'll try out patches
for you if it's something you want to fix.
Anyway, thanks for your help, I'm happy now :)

Chris
