Has anybody had any success with udev?
I need to use oss and have tried to create a udev.rule to connect two identical usb midi interfaces and identify them by the usb port.
I ended up creating the devices in /dev/ and /dev/snd/ and named them /dev/midi1, /dev/midi2 and/or /dev/snd/midiC1D0, /dev/snd/C2D0.
They show up correctly in the folder /dev/ but I don't know how to assign them to anything alsa-base.conf can use.
The first one that gets plugged in is always midi1 no matter where I plug it in. If I plug only one of them into the second usb port it will create midi1 and midi2. alsa-base.conf cannot seem to use the udev rules. It looks like something is assigning the soundcard numbers before or after udev.
Any ideas?

More than udev it might be a modprobe thing. I have these rules in /etc/modprobe.d/alsa-base.conf :
options snd-emu10k1 index=0 options snd_intel8x0 index=1
...which make my Soundblaster card always be hw:0 and the motherboard sound card be hw:1.
