Quoth Microsoft Support
The Code 10 error code is generated when Device Manager has insufficient information or the error that is bubbled up by the device drivers is not recognized by Device Manager. Additionally, this error may occur when one of the drivers that the device needs does not start. If many drivers are being used by a particular device, it can be difficult to determine the one that failed.
