For some reason, the webcam I got today would light up and what not, but the drivers wouldn't work on it and said the device wasn't working. SO I uninstalled it all, brought the camera back and got a replacement. The guy showed me the replacement worked perfectly fine with no problems...But when I brought it home, hooked it up...This time, the drivers and everything installed properly, but the thing isn't lighting up and it sais its not plugged in. I've tried EVERY USB port on my PC, and I know its not the ports because my mouse and other things are hooked up to them. And yes I swapped the ports with the mouse, and nothing worked still. The camera doesn't light up at all, and it sais its unplugged when its still plugged in. Any fixes for this? It's a A4Tech USB 2.0 webcam. And yes, I already tried downloading and installing the drivers from the A4Tech website. Any help = <3
