Verify the cables are properly and securely connected to both the PC and the device.

In some cases the cable may be in the socket, but not fully connected if it was pulled out slightly. For cables like USB, Firewire, or eSATA, it must be fully inserted.

If you have additional connectors on your PC of the same type, you might try another connector. For example, most PCs have multiple USB ports. Try a different port to see if it corrects the issue. Not only does this test a different connector, Windows may re-load the related interface driver.

Reload the device driver as it may have become corrupted and/or is an outdated version.

1. Go to the Device Manager. First select System Properties (Windows key + Break).
   
   For Windows 7 and Vista: on the left side, select Device Manager.
   For Windows XP: select the Hardware tab, then Device Manager.
   
2. Confirm there are no yellow exclamation marks next to Universal Serial Bus Controllers near the bottom of the list. If so, it indicates a problem with the USB hardware or core USB drivers, a different issue than reloading the device driver for your attached device.
3. For your specific hardware device, locate the item in the list. For example, a scanner with problems, may be found under Imaging Devices or Other Devices. Expand the item by clicking on the name or icon. The item should expand to see one or more devices. Click on the specific problem device.

4. The Properties box appears. Select the Driver tab.

5. Select Update Driver and follow the instructions to complete the update. It may require your product's original installation disk.
6. While doing the update if the error message appears indicating the driver is not "Digitally Signed", click continue anyway. Many valid drivers have not been digitally signed (especially for XP).
7. Close all the open dialogs, and restart the system. With luck, the attached device will now function correctly.
