5 * The 5121 is an Atmel AT98C5122 based USB CCID reader (probably the same
6 * design like the 3121). It's CL RC632 is connected via address/data bus,
9 * The vendor-supplied reader firmware provides some undocumented extensions
10 * to CCID (via PC_to_RDR_Escape) that allow access to registers and FIFO of
