In the ideal world, a MITM firmware would export two USB interfaces:

So my next-best idea was then:
* use the CCID reference example from atmel for the card-reader part,
this way standard opensc/openct/pcsc-lite drivers can handle the card
reader like any other card reader
* encapsulate the phone-facing part in the PC_to_RDR_Escape /
RDR_to_PC_Escape messages of the CCID protocol
Another method would be type=vendor recipient=device control requests
over the default endpoint. This works well everywhere except on Windows.
Does this work if the device is already bound by another driver - in
this case libccid?
If so it would probably the simplest of all approaches mentioned so far.
