To fix this problem, reconnect this hardware device to the computer.

The device is not present or was previously attached to the computer. If Device Manager is started with the environment variable DEVMGR_SHOW_NONPRESENT_DEVICES set to 1 (which means show these devices), any previously attached (NONPRESENT) devices are displayed in the device list and assigned this error code.

No resolution is necessary.
