Webcam not detected after sleep, shutdown, or restart
Okay I have Windows 7 64 bit Ultimate edition. I got a Logitech Quickcam pro 9000, I have had it for a while and always had this problem. So the problem is whenever my PC is shut down, restarted, or wakes from sleep my webcam is either not detected, or is detected as a USB 1.1 device, instead of USB 2.0. In order for it to be detected as USB 2.0, or even detected at all, I have to unplugg it and plug it back in. I have all the current software and drivers for my motherboard, windows, and my webcam, in fact I just rechecked yesterday. So, my motherboard is an Nvidia 780i sli. I have looked in the Bios and USB 2.0 is definately enabled. Besides I know it working cause none of my other devices have this issue, plus like I said if I unplugg then plug the webcam back in, it is once again detected as a USB 2.0 device. I have tried all my USB plugs on my PC, and same result. So maybe a bios update? I have the P06 and noticed there is a P10 bios version now. Also when I go into device manager and click show devices by connection, I do not see a USB 2.0 catagory anywhere. Shouldn't USB 2.0 devices be in the USB 2.0 subcatagory? Or is it listed as something different cause of my MB, or Windows 7? Any help would be appreciated, I have just begun using my webcam again lately and it is very annoying, plus when something doesnt work right it just eats away at me till I fix it.
[#0005ff]In Control Panel, find Device Manager and then the USB ports. Go into the Properties of each port in turn and under the Power Management tab, untick the option to "allow the computer to turn this device off to save power", click Apply and OK your way out.
You won't harm the plant too much and one day, perhaps Microsoft will find a way of allowing the computer to turn the device back on after a short sleep.[/#000ff]
