Enable support for the Omnikey CardMan 4040 PCMCIA Smartcard
|

reader.
|

|
||||
This card is basically a USB CCID device connected to a FIFO
|
||||
in I/O space. To use the kernel driver, you will need either the
|
||||
PC/SC ifdhandler provided from the Omnikey homepage
|
||||
(http://www.omnikey.com/), or a current development version of OpenCT
|
||||
(http://www.opensc.org/).
