The Chip Card Interface Device (CCID) function implements a USB
interface that exposes a standard CSCID class that consists of a
pair of bulk IN and OUT endpoints and a single interrupt IN
endpoint. This driver provides a character device interface
allowing a userspace component to be able to provide the
implementation necessary to interface with the smartcard.
