[linux-audio-user] No audio nor MIDI via USB (PlanetCCRMA/FC3/TASCAM US-122)

Dear fellow musicians, I'm trying to get my studio up and running with Rosegarden, but I can't get an audio or MIDI signal in Rosegarden. My distro is Fedora 3 with the Planet CCRMA kernel, and the latest versions of JACK and Rosegarden. I'm using a TASCAM US-122 Audio/MIDI-USB convertor. I've seen some earlier messages in this list about Rosegarden not showing up in the "Readable Clients / Output ports" tab in QJackCtl; that's the same with me, but not of the suggestions so far helped me. The TASCAM_X2Y shows up as readable and as writable client in MIDI, together with MIDI Through-0. Rosegarden only as Writable. In the audio tab, I've got alsa_pcm and rosegarden at both sides, but the only way I can get audio signal is by connecting the Tascam's Line-Out to my soundcard's line-in :-( TASCAM also looks okay in the USB device listing: [root@femoralis ~]# lsusb Bus 005 Device 001: ID 0000:0000 Bus 004 Device 002: ID 058f:9360 Alcor Micro Corp.
