are Installation
USB Cable
There are two types of USB connectors; one is the USB-A, the
other USB-B. The included USB cable is 6 ft. (1.8m) in length.
Power Mode Setting
The Belkin USB 4 Port Hub can operate either with or
without the included AC adapter. When used in bus-powered
mode, without the AC adapter, the hub will supply each
device attached to it a maximum of DC +5V, 100mA power.
This should be sufficient for most mice, joysticks, and other
low-power devices. In self-powered mode, using the AC
adapter, the USB 4 Port Hub provides a maximum DC +5V,
500mA to each downstream port, allowing for connection to
other hubs or power-hungry devices.
