I wasn't entirely sure about the quirk syntax as the two interfaces are at EP 4 and EP5. Does this mean I need to ignore the (non-existant) lower
interfaces? Here's what I came up with:
Does this quirk help anything?
Certainly not; endpoint numbers are not interface numbers. Try with audio interfaces 0 and 1 and MIDI interface 2.
Excellent. I will give this a try and see how it goes. I wasn't actually aware it had MIDI. I guess this may be used for some sort of control function, or maybe it's in the hardware but not supported in the devices firmware.
I'm just asking because looking at the descriptors,it's not clear whether this device does comply to any standard interfaces at all.
Many Roland devices work this way. (And I'd expect any USB audio developer to instantly recognize descriptors like "0b 24 02 01 02 04 18 01 44 ac 00". ;-)
I have to profess my ignorance here.
Thanks for you help. I will report back on how I get on.
