That is interresting, however, I have an older kernel running
an OHCI driver which is able to handle 4 codecs. Same usb
hardware (codecs and hub), but older kernel on a different
CPU, with much less power. This makes me believe that there's a
solution to make it

If sound is ok when using only 1 codec and becomes choppy when adding
a second codec, then it means that this issue is still in the 3.x
kernel. This answer will tell me if it is worth working on using a newer
kernel or not.
I have to say that I'm not a linux expert, so I see the
