driver provides support for the PCCARD based
Omnikey CardMan 4040
The driver provides a character device special file based
Chip/Smart Card Interface Devices (CCID)
The driver implements what the vendor calls the
onto the smartcard reader device.
Reading and writing is synchronous, meaning that a call to
directly corresponds to a complete CCID command sent to the
device, while the following
will return the complete answer from the reader.
There is no support for partial reads or writes.
There is no upper limit on
CCID request or response sizes, but the complete CCID request
must be sent to the driver in
and the complete CCID response must fit into the buffer
are supported and work as expected.
An open file descriptor
will always be ready for writing, but only ready for reading
if the device indicates that it has data available.
