hi, 

i've successfully tested an ESI Gigaport HD+ on the Pi
without clicks with ethernet disable
this interface doesn't have inputs this is why (i think) it could work with USB 1.1

from its user manual specifications, part 5, page 11 : 
1. Interface
- USB spec version 1.1
- USB audio class spec version 1.0
- fully compatible to USB 2.0 host controllers

but this should be tested more longer on the PI

regards

a

Oggetto: Re: [PD] Please help!!

I don't think this is presently possible - I think all 8-channel conforming
USB audio devices require USB 2.0 and the only way to get solid audio in or
out of the Pi (as far as I've been able to get working) depends on slowing
the USB to 1.1 speed.  This is certainly just a software thing and I hope it
will eventually get fixed.

OTOH I've been getting good robust stereo in and out using Griffin iMic (and
there seem to be plenty of other even cheaper choices).

cheers
Miller
