by the way, there's a list of peripherals here with some sound cards verified, I guess you people know about that :)

i just tested this card:

Logitech USB To 3.5mm Jack Audio Adapter ASIN: B0058P0I2C
http://www.amazon.com/gp/product/B0058P0I2C/ref=oh_details_o02_s00_i00

w/ dwc_otg.speed=1 in /boot/cmdline.txt

works between 10-20ms with no clicks with adc~ running various patches
from manual (reverb, octave.divider, etc)

also works in conjunction with my edimax wifi adapter + vnc
screensharing (no need for ethernet cable)

i added it and the beringer to the wiki. others should be added as
discovered....
