It looks like the user doesn't have permissions to read from device 30c9:00e6, so name and serial cannot be determined. Is this the device that you are interested in? Otherwise you can ignore the message. If the device only shows up on the new laptop it could be e.g. a built-in USB camera.
Dear Sir/mdm,
