Dissector for the USB Integrated Circuit Card Interface Device Class (CCID) I've implemented a reasonable subset of a dissector for the USB CCID specification (as described at http://www.usb.org/developers/devclass_docs/DWG_Smart-Card_CCID_Rev110.pdf), during the course of experimenting with an ACS ACR122U ISO 14443 card reader and MiFare tokens. It currently identifies all of the message types listed in that specification,ng. From me: * Fix Clang Warning * Remove trailing whitespace from lines * Fix Checkhf (Remove a unused entry) * Added packet-rfid-mifare to Makefile.common and CMakeLists.txt svn path=/trunk/; revision=39750
