Driver for USB Web-camera?

Question

I'd like to use a cheap web camera as an input device to Labview so that
I can play with the image processing features.
Does anyone have a driver for something like that? I've looked at the
NI web site and I haven't found anything for USB. Lots of firewire, IEEE 1394,
but no USB.

That's a joke, right? Very hard? Other that the very specific USB drivers
that Iomega provides with their USB zip drives for WinNT, there are no drivers
for USB for WinNT. There was some software developer down in India that
allegedly had USB drivers for NT and like a fool I tried to use them. Zoowie,
I get to reformat my hard drive. Complete and total system disablement (?)
If you know of any USB driver for WinNT let us all know. I for one have a
large financial and personnel commitment to NT and don't have any plans of
switching to Windows 2000 any time soon.
