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

[Oscar]

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 at femoralis ~]# lsusb

Bus 004 Device 002: ID 058f:9360 Alcor Micro Corp.

Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000


As far as I can see, all proper modules are loaded as well:
