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:
------------------
Rosegarden 4-0.9.7 - AlsaDriver - alsa-lib version 1.0.4

------------------
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
