View Full Version : USB and Firewire cameras - Differences?

Forgive me if this comes through twice -- apparently, a timeout had logged me out before hitting Send...

I have software written to support the Firewire cameras using the C++ Class library. I also support generic WDM, but this leaves a bit to be desired as, as far as I can tell, one cannot do things like set the exposure duration directly via a standard WDM call. I now have users that have USB cameras and they have been working off of the WDM driver rather than the specific TIS / Firewire / C++ Class library version.

Do they have to do this or does the C++ Library support the USB cameras as well? If so, are there any differences? If a user has one firewire and one USB on there, would getAvailableVideoCaptureDevices() nicely return a list of two and one would never really know that one is Firewire and the other USB?

IC Imaging Control Professional supports all WDM stream class devices, regardless of firewire or USB.

IC Imaging Control doesn't even know whether a device is connected via firewire or USB.
