The bInterfaceProtocol field is a number value from the CCID USB descriptor: Protocol code
USB-ICC devices are USB devices with the same chip for reader and smart card. They are aften called token.
They follow a different USB specificiation: "Device Class: Smart Card ICCD", Revision 1.0, April 2005.
According to this specification:
Version B ICCD tokens are:
