i am sloppy and the systems i use this lovely piece of h/w is not what you&=
#39;d call the latest and greatest

so (my) the state of things at the time of this writing, is the following:<=

- on 3.4.x-rt it still works but only like a plain usb1 device (-r48000 -p1=
28 -n3); good old and awesome, special fast and low-latency rawusb/hwdep mo=
de of operation is dead. or it seems so

- on 3.8.x-rt it doesn't work at all; always nagging the device's b=
eing used by something else (and no, it's not pulseaudio:); and if you =
dare to use jack1 then, well, it just crashes the whole show (kernel oops)<=
br>

only tested with preempt_rt though (thus the -rt suffix above)...

i know this does not help in anything but at least you're not alone :)<=
br>

cheersThis is a known issue with the 3.8 kernel. It's breaks not o=
nly tascam but lots of other USB audio devices as well. Register your disco=
ntent with your distro, I guess.

Ah - I was about to post a separate thread about this=
- can't get my focusrite saffire to start at less than 512 on a 3.8 ke=
rnel.. Will go down to 64 on 3.5. Where do I report/add to this bugreport?<=
