Hi,

I have purchased 2 of the same usb video capture devices with the intent of getting 2 different video feeds in to the pc. Currently the software I am using to look at the feeds only sees a single device despite windows hardware manager seeing both. Not being a programming expert I am assuming that the problem here is the driver for the capture device? Has anyone any suggestion as to how I can get this to work or do I just buy 2 different capture devices with different drivers?

Use Nlite and integrate your drivers in the original windows.

How is that supposed to help him with a device that is already functioning on an installed system????

Chances are the software either only handles one device, or for some strange reason sees them both as a the same device.

I tried contacting the manufacuter and they were not much help. The makers of the software I am using in which I am trying to see more that one vide feed also think that the restriction is Windows, for now I have two different usb to video digitizers by two different manufacturers and that works fine. As I need to see about 8 to 10 video feeds then it looks like I will need 8 to 10 different brands of adaptor. I would have lke to kept them all the same but if I can;t get two working under Windows then I doubt that I will have much chance wth 10!!

Maybe, just maybe, if the drivers are "monolithic" or however, even if multiple files, do not have "cross-references" between them, you could try renaming the driver(s) and create as much as modified .inf files as needed.

Say that you have a driver called videofed.sys and a videofed.inf file for it, you can try making a copy of both, then:
1) rename copy_of_videofed.sys to videofe1.sys
2) rename copy_of_videofed.inf to videofe1.inf
3) edit videofe1.inf replacing all occurencies of videofed.sys to videofe1.sys, edit also the description in [Strings] section

Not easy, not necessarily working, but worth a shot.

An app to edit .inf files:

(but you can use notepad allright)
