EDIT: moved to new topic, for clarity
I'll take a look later today....
what are you running on ? (Windows/Linux/Mac?)
I need more details about the device (aka midimix) , can you connect it to your PC/Mac so we can get more details in particular, once connected
if your on Mac, can you run
if your on Linux...
on windows,not sure what to use
suggest USBView ...
(sorry, I don't do windows unless I have to )
basically, I want to know what interfaces it has available....
(Im guessing its supports something over and above midi, that perhaps is not being picked up by the firmware, but I need to see what its reporting first)
Of course with the above, I just need to know about the one device, I don't need to know about all your USB devices, i.e. you can trim the output
