Hi, I've managed to get as far as the following entry
appearing in /proc/asound/cards when the device is
present:
[root@BILLSDELL root]# cat /proc/asound/cards
0 [U8 ]: USB-Audio - U-8
Roland U-8 at usb-00:1f.2-1, full
speed
................
So it would appear to me that the code in usbaudio.c
has discovered the hardware ok, am I right or have I
missed something?
Assuming the device discvery is ok I'm now trying to
figure out how to connect Jack to this, specifially
whats the device? should it show up as HW:0 ??? any
pointers would be appreciated. Sorry, I know it's a
stupid question!
Here is the lsusb output and the modules.conf in case
its of any use to anyone. Thanks for providing such a
great resource:
