There is definately a USB/CCID trend here. Even we built a reader board that is designed for an optional (Phillips) USB-on-the go chip, turning the card reader into a reverse controller, so reader controller can talk unto n CCID-based ICCs via its USB port. Bye bye 7816. For military models, you exploit the USB2 security modes, which can implement the secure messaging CCID facility, effectively, in a high-speed USB2 hub environment with low-speed endpoints.
CCID is a good start for national id cards. Making CCID and USB-on the-go it work with today's actual $5 commodity technology took a lot of fiddling, and stack tuning. Its not a panacea. Getting a legacy reader to work was probably less effort, but...you have to do it for each reader, for reach firmware version, and each linux kernel build...
The more folks add workarounds and "vendor-additions" to CCID, the more we are going to end up with the same mess as in the legacy 7816 world. I dont care whether its muscle or Microsoft that sets the standard, note. Nothing stops a reader offering two USB configurations, so a client can choose between the commodity and enhanced CCID module, to faciliate the competitive environment.

You can turn ON all debug information with the configure script of the ccid drivers.
"./configure --enable-debugperiodic=yes --enable-debugcomm=yes"
