Poking around in the code, there is a UAUDIO_MULTIPLE_ENDPOINTS #define that is commented out. Compiling with that defined gets a little more info -- it appears that the underlying USB layer is not providing multiple endpoints for a specific interface. I'm turning on debugging and seeing if something is getting confused in reading the hardware configuration or if its a dumb bug. The code certainly appears to try iterating over the endpoints. -- Doug White | FreeBSD: The Power to Serve dwhite@gumbysoft.com | www.FreeBSD.org
