  3. Under Universal Serial Bus Controllers, a Universal Host Controller and a USB Root Hub should be listed.

    If the Universal Host Controller or USB Root Hub has an exclamation mark next to it or a red X on the icon , there is a problem with the USB Controller. Contact the computer manufacturer for information on how to fix the USB controller.

    If the Universal Host Controller or USB Root Hub does not have an exclamation mark next to it or a red X on the icon , please leave the Device Manager window open and continue.

Ensure that your system has the latest USB chipset drivers installed. Please use the following steps to help determine your computer's USB chipset manufacturer.

  1. Under Universal Serial Bus Controllers, a Universal Host Controller and/or an Enhanced Host Controller should be listed. The name listed for the controller should be the manufacturer of the USB chipset. Please refer to the illustration below.
