Are you sure ?
I bought an Audiophile USB a few months ago, I seem to remember it is
USB 1.1 only...
(or did M-Audio release a new one?)

I confirm: according to
  http://www.m-audio.com/products/en_us/AudiophileUSB-focus.html

USB recording:
 	• 16-bit/44.1kHz > 4-in/4-out
 	• 24-bit/44.1kHz > 4-in/2-out or 2-in/4-out
 	• 24-bit/48kHz > 4-in/2-out or 2-in/4-out
 	• 24-bit/96kHz > 2-in or 2-out
 	                      ^^

I also has trouble with the Audiophile, but hadn't have much time to
test it for quite a long time now. As soon as I find time to compile
kernel 2.6.14, I'll give it a try with all this new information.
