Thanks again for your help. I submitted a bug report to the Ubuntu
kernel package maintainer and CONFIG_USB_BANDWIDTH is no longer set in
the default Ubuntu kernel (fixed in 2.6.12-5.5). I also managed to make
this work under 2.6.11 by increasing Periods/Buffer to 2, Frames/Period
to 2048 and choosing "Force 16 bit" in Jack.
It works ok but with high latency (~90ms). This is OK for me, I'm a
hobbyist. Also from what I understand USB audio has problems with
latency under Jack.
Thanks again,
Peter
