[LAU] USB audio device and JACK

Hello everyone! I had a USB audio device here, a Zoom h4n, portable recorder/audio interface. When I connect it to my box, it shows up and ALSA finds it. First: ALSA can't open the mixer, no elemtns found, alsamixer says. Second: I can't use JACK with it, although I read on some forum, that a chap managed with Fedora FC6. JACK tells me something about broken pipe. It runs, but there's no sound and I definitely have to "killall -9" it. :-( I tried JACK with different period sizes (-p) and different frames per period (-n), different samplerates, although I can set these on the Zoom, before I connect it. As I said: ALSA can record from it and play sounds using it. Does anyone of you have an idea on the subject?
