Webcams may need a driver.
Generally (portable) digital cameras (Canon, Nikon, Olumpus etc) don't need a driver. When you want to download their pics, most just plug in via USB and they act like a removable external disk drive -- or you remove the picture card and insert in computer's card adapter.
Call me a snob, but if your camera has no branding, chances are it ain't worth bothering with.
Try plugging it in and see what Windows' New Hardware Wizard makes of it -- it may reveal a brand name or model number when it requests a driver.
