I wrote a driver stack for this device for MacOSX already and attended the development for the Windows version. They both work fine and so I have some code to orientate on. > The driver currently assumes that each (output/input) PCM endpoint > has its > own interface (where it can select alternate settings independently). > Is this the case? No. All audio data is muxed and sent over one single endpoint and receviced from another. I think I have to write it from scratch to keep it straight forward. Thanks for your suggestions, let's see how far I get. Daniel ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
