[linux-audio-user] Problems with Roland PC-300

[Chris Norris]

Hi all - I would appreciate if someone is able to help get my Roland 
PC-300 midi keyboard controller to work.

The short problem seems to me that although the keyboard is being 
recognised via USB OK, it is not being correctly/completely identified 
by ALSA.

When I plug it in I get in my system log:
Nov 28 17:17:57 dukla kernel: usb 3-2: new full speed USB device using 
uhci_hcd and address 3
Nov 28 17:17:58 dukla kernel: midi: probe of 3-2:1.0 failed with error -5
Nov 28 17:17:58 dukla kernel: midi: probe of 3-2:1.1 failed with error -5
Nov 28 17:17:58 dukla kernel: usbmidi: found [ Roland PC-300 ] 
(0x0582:0x0008), attached:
Nov 28 17:17:58 dukla kernel: usbmidi: /dev/midi00: in (ep:81 cid: 0 
bufsiz:64) out (ep:01 cid: 0 bufsiz:64)
Nov 28 17:17:58 dukla kernel: usbcore: registered new driver midi
Nov 28 17:17:58 dukla kernel: usbcore: registered new driver snd-usb-audio

Even better, it shows up as a device:
me at dukla:~> cat /proc/asound/cards
0 [V8237          ]: VIA8237 - VIA 8237
                     VIA 8237 with ALC658D at 0xe000, irq 177
1 [PC300          ]: USB-Audio - PC-300
                     Roland PC-300 at usb-0000:00:10.2-2, full speed

And yet I cannot see it as an input ALSA device:
me at dukla:~> aconnect -i -o
client 0: 'System' [type=kernel]
0 'Timer '
1 'Announce '
client 62: 'Midi Through' [type=kernel]
0 'Midi Through Port-0'
client 128: 'FLUID Synth (10018)' [type=user]
0 'Synth input port (10018:0)'

I am running SuSE 10.0 x86_64 (kernel 2.6.13-15) which has ALSA 
1.0.9-23. My skills do not run to kernel compiles: the keyboard does 
work fine under Windows and even
cat /dev/midi
shows some garbage at each key press.

Any/all help or suggestions would be very welcome!
Thanks
