Remarks
Bits 3-2: Method for CCID Time Extension (empty) data-blocks
The Time Extension frames are mandatory with the CCID driver from the PC/SC-Lite project.
Bit 1: Implement CCID without the Interrupt endpoint
The Interrupt EP is mandatory with Windows PC/SC driver and most SpringCard-supplied CCID implementations. It shall be disabled only when the product is used with a legacy CCID driver that has a bogus Interrupt implementation.
