OK, the device. But to me it looks like, the audio interfaces are detected correctly as well. -------------snip-------------------------- T: Bus=01 Lev=02 Prnt=02 Port=03 Cnt=01 Dev#= 3 Spd=12 MxCh= 0 D: Ver= 1.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 2 P: Vendor=1107 ProdID=0102 Rev= 1.00 S: Manufacturer=CreamWare GmbH S: Product=CreamWare Noah Synthesizer C:* #Ifs= 1 Cfg#= 1 Atr=c0 MxPwr= 0mA I: If#= 0 Alt= 0 #EPs= 6 Cls=ff(vend.)

Don't ask me from whom. lsmod won't tell me.

Might the patch(the code in it) for usbaudio.c you posted before be helpfull for the program? BTW: How many devices/"cards" is the snd-usb-audio driver able to handle?
