One of the nice things about these older Logitech Webcams is that they don't require a driver download and they support Windows Image Acquisition (WIA) directly. WIA is an API included in Windows that aims to unify the acquisition of images from all kinds of devices, including scanners and cameras. This is a pretty low-level API and a bit of a hassle to us. However, after Windows XP SP1 the WIA Automation Layer was released with a simpler COM API meant for VB6 and ASP developers. You can download this layer from MSDN and other places as it is free for redistribution. The meat of the layer is the wiaaut.dll that should be copied into the system32 directory and registered via the command "regsvr32 wiaaut.dll."
