A small red x next to a hardware device in the Device Manager means that the device is disabled. It could be that you disabled it, or Windows might have disabled it because of a problem with the device. To remove the red x, just enable the device again. If there are issues with your device, you’ll see a yellow exclamation point next to the device instead of the red x. Click here to read what the yellow exclamation point means.
*Disabled devices also generate Device Manager error codes. The error in this case is a Code 22.
