[linux-audio-user] ordering usb sound cards

I've read some of Christoph Eckert's posts from 2005 about passing index options to snd-usb-audio when it gets loaded, but I haven't been able to get it to work. There is a builtin mic with the non-functional camera that is apparantly on the usb bus, the internal SiS AC'97 device and sometimes an edirol ua-25. Any one of them can end up in any position. I've tried messing with options in modprobe.d, but haven't figured out how to make the cards stick to their card numbers on each boot. Anyone here have some pointers? It'll make the LAC streaming go much more smoothly if I don't have to hunt down which cardnumber is the edirol for the audio streams and which cardnumber is internal for monitoring. Thanks for any help, ERic Rz.
