IV. Power Mode Setting
There are two power mode options for the GE Rotating USB 2.0 4-Port Hub.
The first is self-power mode (recommended), which requires the use of the optional AC power adapter (Available at Jascoproducts. com). In this mode, each port is provided with 500 milliamps, allowing for additional hubs, cameras and other high-powered devices.
The second is bus-power mode, which does NOT require the use of the optional AC power adapter. In this mode, the hub is provided with 500 milliamps for all 4 ports. This should be adequate for mice, keyboards, and other low power devices. If you are not sure or if device performance is poor, use the optional AC adapter. When using the optional AC power adapter, make sure the plug is properly con- nected to the hub and to a standard electrical outlet. GE Surge protection is recommended.
