This is an OS X driver for MIDI devices connected via USB. It has been tested with a Roland PC-300 MIDI Keyboard under Mac OS v10.8.2 (Mountain Lion) as well as with v10.9.1 (Mavericks)
Sorry for the comment, the driver Do work on OS X 10.9.2. It turned out to be just a conflicting driver in the same folder, and when I removed it the PC-300 was detected as intended :)
