Hi All - Thanks to the assistance of Nick Dowell at Focusrite I have working MIDI over USB for Novation ReMOTE 25 Audio AKA X-Station. The attached patch builds and runs cleanly using the latest Fedora Core 3 update kernel (2.6.10 #741). I don't have the MIDI only device or the Speedio to test with but if they operate as Nick describes these should also do MIDI over USB with my patch. I don't think I broke anything but if anybody can check out this patch with other devices, particularly Roland and MIDIMAN devices I'd be much obliged. Thanks, ccb
