Apply Pete Goodeve patch, provided in #4463:
* add output support * fix variable lenght input: all usb_midi_event_packet bytes were always returned before. Missing features are: * multiport support (input from any ports are read and merged currently, so beware to connect only one port!) * non-standard USB midi adapters, like my Roland UM-2 which don't advertize themselves as Audio / Midi stream class/subclass. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33126 a95241bf-73f2-0310-859d-f6bbb57e9c96
