The underlying hardware supports 9 endpoints: - EP0 - 4x IN EPs - 4x OUT EPs Currently the driver assumes every EP number is unique. This limits the amount of EPs to 1 + 4 = 5. Utilize the EPs in such a manner that all may be used. Also fix a few error handling related bugs. Update the composite driver to match the current situation as well.
