Notes :

To activate the USB hub function, the 

Speaker/USB HUB Option

another hub with the USB cable(enclosed).
When connecting the USB cable, check that the shape of the connector at the cable side matches the shape  at the connecting
side.
High powered devices (such as stand alone scanners and camera’s etc.) can not be connected to the USB HUB ports. Self
powered devices (use an extermal AC adapter to meet the high power repuirement) can be  connected to the USB HUB port.
The USB HUB is compliant to the USB 2.0 Specification and will support low speed and full speed devices (same as USB 1.1).
The HUB can not support high speed devices and will connect them as full speed devices.
