Patch 7 has changes on how to transmit IN USB requests. It implements a FIFO of pre-allocated usb requests and uses then as needed, instead of allocating then on demand. This is my initial implementation and is open for suggestions and comments. Patches 1-6 is pretty much straight forward. changes in v4: - pre-alocation of in requests. - more code clean up - fix memory leak on out requests - configure endpoints only when setting up MIDIStreaming interface Felipe F.
