[linux-audio-user] novation remote 25 usb midi controller

[Eric Dantan Rzewnicki]

I thought I had installed hotplug, but apparently I forgot. After
installing it the uhci driver loads. However, still no midi. After
stopping alsa and then hotplug and then starting hotplug and alsa via
init scripts I see this in /var/log/messages:

box1:~# grep "\(usb\|uhci\)" /var/log/messages
.....

Jul 31 16:31:06 box1 kernel: usb.c: registered new driver snd-usb-audio

turning the remote 25 off and back on yields this:

Jul 31 16:35:14 box1 kernel: usb.c: USB disconnect on device 2
Jul 31 16:35:27 box1 kernel: hub.c: USB new device connect on bus1/1,

Jul 31 16:35:30 box1 usb.agent: ... no modules for USB product
1235/4661/101

aconnect doesn't show anything either:

box1:~# aconnect -i   
client 0: 'System' [type=kernel]
    0 'Timer           '
    1 'Announce        '
box1:~# aconnect -o 

But, at least it shows up on the USB bus now:

box1:~# lsusb
Bus 001 Device 001: ID 0000:0000  
Bus 001 Device 003: ID 1235:4661

box1:~# cat /proc/bus/usb/drivers 
         usbdevfs
         hub
         snd-usb-audio

Is there any other info I could provide that might help? 

Steve mentioned that i might need the snd-usb-midi driver instead, but
if i remember correctly it was merged into the snd-usb-audio driver a
while back. Is that true?

Are there some options I'm supposed to pass to snd-usb-audio via
modules.conf?

I've read about special case quirks being added for specific usb
devices, but haven't understood what they are... Could that be possible
with the remote 25?

Thanks for your help,
Eric Rz.
