Basically, you first need a kernel module for doing the hardware
access of the card. Depending on the way the kernel module is
written it's often quite useful to have a library that supplies a
simple API instead of communicating with the module directly, e.g.
via ioctl() calls. If a kernel module exists and you also have a
library, using the card is quite simply done by calling functions
in the library according to the documentation that hopefully comes
with the library.
So the question is: does the card comes with a kernel module and
possibly a library? Or do you have to write everything yourself?
And what kind of card is this and what are you planning to do with
it? Without knowing on which level (i.e. module, library or userland
program) you want to deal the card it's more or less impossible to
figure out what you're looking for.
