OHCI on IEEE 1394

Hello,

We are developing a standalone device that communicates
via 1394 with a PC. The device has OHCI compatible 1394
device. I installed 1394 board in the PC and windows
2000/XP found it. The ohci1394 driver is attached to it.
Could you tell how I can find out what are interfaces of
ohci1394 driver and how I can communicate with it in C/C++
from user mode?

There is no published interface for communicating directly with the port
driver from user-mode that I am aware of if that is what you are asking. I
assume from your description that this is an OHCI host controller?

What information exactly are you hoping to get from this device?

Hello Bill,

Thanks for responce.
We are developing a standalone device that would be
connected to a PC via IEEE 1394. We are planning to use
isochronous mode of operation. The SW on PC should be able
to receive the data and process it.

Gagik.

Hello Rony,

I assume that 1394 wdm is another 1394 kernel driver
(.sys) which I probbably can install on my computer. But
there is already a driver installed on Windows 2000/XP. I
just want to use the interface of that driver.

Thanks,
Gagik.

In that case, then it sounds like a regular 1394 device. If so, then the
only way a driver should have loaded for it, is if it belonged to a
predefined device class which has native drivers like the image class. Is
this device a camera or some such? What is the unit spec ID and sw version
for this device?

If the device does not belong to a predefined class, you will have to write
your own WDM driver for it.

This driver provides no interfaces accessible from the user mode.

It only provides the interfaces to other kernel mode device drivers which are
loaded by PnP for particular 1394-attached hardware. So, you must have some
1394 hardware with valid config ROM and write a kernel-mode driver for it.

Another way - supported since XP - is "virtual 1394 device". This is a kernel
mode driver connected to 1394 stack which adds a unit directory to the
machine's config ROM, thus exposing the machine itself to the 1394 bus as some
emulated device. It will then receive the indications when other bus nodes will
try to access this device.

For "virtual 1394 device", you will need no hardware.
