From: Stefan Fritsch <stefan_frit...@genua.de>
- We want to support both T=0 and T=1. Additionally, note that all
fields in USB descriptors are little endian and the supported
protocols are in the lowest byte the of the 32-Bit dwProtocols field.
- We want APDU level exchanges. This saves us from PPS exchanges and from
APDU reassembly from T=1 packets.
