Typically two things are required for a USB device to work - a driver, and an appropriate udev rule to associate the driver with the device. Do you have USB midi support enabled in the kernel? If so, is there a udev rule for USB midi devices? If there isn't, presumably you could just use Ubuntu as a reference for that.
