My webcam is not recognized and I get a message that says that the camera is not turned on. I cannot find the device in my device manager in order to repair it and the driver. I need help! I can be...
You should first verify that the USB port can recognize a USB memory stick i.e. verify that the USB port hardware is working. If its is not, use Device Manager to reload the USB Host Adapter drivers.
If this is an external USB device (laptop or desktop) ...
the Device Manager will always locate the camera, if only as an Other Device or sometimes with the wrong driver in another device class. One possibility, if the host PC is a laptop, is check the Power Scheme. Set this to Always On, as this is supposed to (but not always..) stop Windows from turning off external interfaces (such as USB) to conserve power.
Check if the camera will appear in Device Manager on another PC. This will verify that the camera hardware is functional.
If this is a laptop built-in WebCam, it will usually appear in Device Manager under Imaging Devices. If it does not, I'd suspect that the camera hardware has a problem.
Let's assume that this is an external USB Camera. When the camera driver is loaded, the driver INF file is copied to a new file
C:\Windows\inf\oem.inf where is an arbitrary number.
When you plug in the camera, Windows PlugandPlay looks in C:\Windows\inf for the correct driver to assign to the device.
Windows can get confused about drivers, esspecially if you have attempted to reload the driver, or load a newer version.
If you do a search for all C:\Windows\inf\oem*.inf containing "Toshiba" or "WebCam" you should be able to locate one or more oem*.inf files that is the installed driver for your webcam.
Lets say this file is oem31.inf Delete this file and also oem31.pnf if its present.
This removes the last driver that was installed. Now, run Device Manager, and plug in the camera. If Device Manager can locate the camera (as an Other Device to start with), you should be able to reload the correct driver, either from the installed driver directory (if there is one) or from you camera CD.
