24 help
25 Enable support for the Omnikey CardMan 4040 PCMCIA Smartcard
26 reader.
27
28 This card is basically a USB CCID device connected to a FIFO
29 in I/O space. To use the kernel driver, you will need either the
30 PC/SC ifdhandler provided from the Omnikey homepage
31 (http://www.omnikey.com/), or a current development version of OpenCT
32 (http://www.opensc.org/).
