Recommended resolution

This problem occurs if you install a driver for a non-Plug and Play device, but Windows cannot find the device. Here are some things that you can try to resolve this problem.

If the Troubleshooting Wizard does not resolve the problem, do one of the following:

* If the device was removed, uninstall the driver, connect the device, and then click Scan for hardware changes to reinstall the driver.
* If the hardware was not removed, the driver files might be obsolete. In this case, update the driver from Device Manager. In the device Properties dialog box, click the Driver tab, and then click Update Driver to start the Hardware Update Wizard. Follow the instructions to update the driver.
* If the device is a non-Plug and Play device, you may have to install a newer version of the driver. To install non-Plug and Play devices, use the Add Hardware wizard. Click Start, and then click Run. In the Open box, type hdwwiz.cpl.
