...but it's software...
You don't need the software included with many USB devices, at least not for anything newer then Windows 98SE; most devices identify as a "class" of USB devices; for example a camera tells the computer it's a camera, a thumb drive says "I'm a storage device" and all modern OS's know how to communicate with devices of each class. Camera's are sometimes different; for example when I plug in my Samsung L100, the computer doesn't detect it at all unless the camera is on (not surprising) but I also have to choose a option on a menu that the camera presents: I need to choose wether it's connecting to a Computer or to a Printer.
This is somewhat important since not all camera's present the option; with "Computer" it shows up as a standard Mass storage device- I cannot use it as a camera or webcam, for example; it isn't detected as one, merely as a hard drive.
When I say "printer" however, the camera "connects" as if it was a camera, and supports camera-like actions like Picture Transfer Protocol and pictbridge. I assume it would be usable as a webcam but the camera connects and disconnects constantly so I can't find out much more about it then Windows 7 stating it found a Digital Camera constantly.
This is somewhat relevant here because some older cameras don't support use as a Mass storage device; even certain models in a line might not, and in those cases they would need the "special software" to be used. I doubt that is the case here; they almost always show up or can be made to show up as mass storage devices, and worst case scenario means you would need a Card reader to read the SD card (or whatever the camera happens to use). Unless of course the camera happens to be old enough to use a Serial or Parallel cable... in which case best of luck!
