IEEE1394: Virtual device. Virtual adapter?

i've built and installed the IEEE1394 sample drivers that add a virtual
device to the firewire bus. And i run UI app and see my activity when
i do stuff.

But i do not have an actual FireWire/IEEE1394 adapter in my system.

Later, i installed the driver for a digital camera, and use it's GUI app to
try to talk to a camera.

Should i see activity in the DDK debug app coming from the digital
camera app? i do not see anything in the debug app's log when i have
the camera program try to "find a camera."

Am i doing something wrong with the ddk's debug app? Should i be
able to see activity? Will XP have the drivers in place for the firewire
adapter to host my virtual device? Will the camera program interrogate
the drivers in the absence of an actual FireWire adapter?

Or do i need to actually install a firewire adapter in my system?


i hope my question makes any sense.

The 1394 bus driver stack will only be loaded when a 1394 host controller is
enumerated by the pnp manager. Without the 1394 bus driver stack, you are
not going to get a 1394 virtual device enumerated. You MUST have a 1394
OHCI compliant host controller plugged into the system to make this work.

I am curious as to how you installed a 1394 camera driver with no 1394
camera device present??

i installed a device driver for IEEE1394 digital cameras.

http://www-2.cs.cmu.edu/~iwan/1394/

The driver is installed with a standard .inf file.

The install process didn't complain, so i assumed it installed okay.

i didn't realize that the driver simply won't work without a FireWire
adapter installed. i had hoped that XP would still have all the various
drivers running, so i could still use virtual devices - and the camera
software simply "wouldn't find" a camera on the bus.

PnP drivers should not be installed this way. Drivers for devices like ISA
devices that the system can neither discover nor query require some user
intervention to make the system aware of the device and its resources. In
general, plug-and-play devices are automatically discovered by the system
and then you are prompted for an INF (there are ways to install a driver
ahead of enumeration, but the driver won't load until the device is
enumerated in any case). So, you can't do what you are trying to do.
Virtual 1394 devices require that a 1394 host controller be enumerated and
functioning.
