In the ideal world we would have a multi-function USB device exporting separat interfaces for this, but the sam7s only supports 4 USB endpoints and thus we have to somehow tunnel the "card simulation" part through those Escape commands of the CCID profile.
It's also possible to use vendor-specific control transfers independently of the interface.
yes, but I think the size of the endpoint and the overall nature of control transfers might not be the best solution, in terms of transfer speed.
