You don't need to put the driver into the blacklist to force a
particular ordering. Just make sure that all driver modules have
correct "index" parameters in /etc/modprobe.conf (or whatever module
configuration file your distribution uses):
options snd-whatever index=0
options snd-usb-audio index=1
I load the driver and firmware with this script:
modprobe snd-usb-audio
fxload -I /.../ezusbmidi2x2.ihx -D /proc/bus/usb/001/003
In theory, snd-usb-audio should be loaded after the firmware.
Can I automate this so I don't have to use the
script ?
Put the script into /etc/hotplug/usb, and create another file named
scriptname.usermap containing the vendor/product IDs of the device.
The files I'm using in the loader for M-Audio's closed source firmware
are available here:
<http://cvs.sourceforge.net/viewcvs.py/usb-midi-fw/midisport-firmware/>
2. The firmware script requires a USB ID. Is there
some way to have
the script find that number, instead of me having to look it up via 'cat
/proc/bus/usb' ?
The kernel passes the usbfs file name to the hotplug script in the
environment variable DEVICE. (fxload will use this variable by
default.)
3. More of a seq24 problem, but: When I start
seq24 and load a
previous session I *must* have my synths loaded in their original order,
else I have to reassign every sequence port/channel to the new ordering,
which can be a real pain. Is there anyone else who would like to see
more flexibility in relocating device numbers ?
You could try "modprobe snd-seq-dummy ports=10" and connect those
ports by hand to your synths, but then you'd have quite unintuitive
port names.
I'm thinking that it's much easier to redefine
one device's ID
Currently, ALSA doesn't allow to choose/change the client number of
software synthesizers.
than to redefine potentially hundreds of sequence
patterns.
It would be nice if sequencers would support assigning ports by name.
The MMA has defined a meta event for this, but AFAIK nobody uses it.
