I don't know how you are getting on with this problem. snd-mpu401 should show up in, /lib/modules/your_kernel/sound/drivers/mpu401, if it is there. I read there were some problems with snd-usb-audio in 2.6.14, and the basic version of 2.6.15. In later revisions of 2.6.15 this problem is fixed. Whether midi was involved I don't know, but it might be worth trying an earlier version than 2.6.14, or if it is available for you, one of the later revisions of 2.6.15. While your at it, see if you can modprobe snd-usb-audio with your 2.6.14 kernel. It would be interesting to know if it works. Nigel.
