Yes, this looks like a typo. However, the USB interface for the MIDI ports should be number 3 (0-2 are for the PCM audio part), but your device doesn't have interface #3: > D: Ver= 1.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1 > P: Vendor=0582 ProdID=0026 Rev= 1.01 > S: Manufacturer=Roland > S: Product=EDIROL UA-20 > C:* #Ifs= 3 Cfg#= 1 Atr=80 MxPwr=170mA > I: If#= 0 Alt= 0 #EPs= 0 Cls=01(audio) Sub=01 Prot=00 Driver=snd-usb-audio > I: If#= 1 Alt= 0 #EPs= 0 Cls=01(audio) Sub=02 Prot=00 Driver=snd-usb-audio > I: If#= 1 Alt= 1 #EPs= 1 Cls=01(audio) Sub=02 Prot=00 Driver=snd-usb-audio > E: Ad=01(O) Atr=09(Isoc) MxPS= 192 Ivl=1ms > I: If#= 2 Alt= 0 #EPs= 0 Cls=01(audio) Sub=02 Prot=00 Driver=snd-usb-audio > I: If#= 2 Alt= 1 #EPs= 1 Cls=01(audio) Sub=02 Prot=00 Driver=snd-usb-audio > E: Ad=82(I) Atr=05(Isoc) MxPS= 192 Ivl=1ms This is strange. Does the MIDI port work in Windows? Clemens ------------------------------------------------------- This SF.net email is sponsored by: SlickEdit Inc. Develop an edge.
