Something that should improve a lot :

add the option nrpacks=1 to the module snd-usb-audio and check this :
$ zcat /proc/config.gz | grep -e CONFIG_EXPERIMENTAL -e USB_BANDWIDTH

if the output is this :

CONFIG_EXPERIMENTAL=y
# CONFIG_USB_BANDWIDTH is not set

you are okay :) You can put a period of 3 to jackd and tweak the frames as
you need.

if not, good kernel compilation !
