I have two webcams, one by Nexxtech and another by MIOS - rather non-descript USB Camera. The Nexxtech camera seems to need a driver - I have installed it. But the MIOS likely uses the one in Win XP SP3. Why is that? Why won't one driver work for both cameras? Rationale: I want to develop some software to process the live video, but could one piece of software be used for both cameras? I am a noob about web cams and video processing. Regards, Lou.
