Sometimes Messages telling you that a particular device can perform faster will appear.
This is true especially on Aspire 4530 Webcam.
The reason is the WebCam is attached to a Full-Speed USB port which allows less data transfer rate then a High-Speed USB port.
To correct this simply uncheck the option:
Go to Control Panel Device Manager
Open the USB Control Hubs until you see one of these dialogue boxes.
Uncheck and Save.
