Re: [USB] composite device


Joseph, Jithu
 

By composite device I think you are referring to USB device configurations which support multiple interfaces.

I took a quick look of the USB stack, and it seems that presently we support single interface configurations only.

Few things I found missing are:
-> provisions to specify class handlers for multiple interfaces
-> switching class handlers based on the directed interface of incoming requests
Those are probable areas you can look at if you are interested.

More analysis is required to gauge the effort involved in making the stack multiple interface aware .

Thanks
Jithu
