I am trying to intereact with the FireWire bridge

I am trying to interact with the custom hardware connected to the FireWire bridge through a FireWire PC Card in a PC running Win 2K. I am confused in the sense do I really need a WDM driver on top of the Sbp2Port.sys to communicate with the hardware or can I use certain IOCTL commands to bypass the bridge and directly send commands to the custom hardware.

Can any one help me with this problem.

Thanks in advance.

In order to interact with a custom hardware you have to develop a WDM device
driver that talks to the 1394 bus driver (1394bus.sys) at its lower edge and
provides a custom API (IOCTLs, read, write) at its upper edge. You could use
the 1394diag sample driver that is included in the DDK. However, the
sample’s implementation is ugly. It is useful for simple testing purposes
only. It provides very bad performance because it behaves synchronously.
Alternatively, you could take a look at our product VHPD1394, see
