usb audio

[Landsberger Brian J]

	Has anyone been able to get the Apple Pro (the round clear) speakers to
work in Linux? I've read the howto's and followed the various steps to
no avail. The various usb modules print the following to syslog:

Feb 17 14:05:50 fux0r kernel: usb.c: registered new driver audio

Some info out of usbdevfs on the speakers...
