IV. Power Mode Setting
There are two power mode options for the GE “Executive Series” USB 2.0 7-Port Hub.
The first is self-power mode (recommended), which requires the use of the AC power adapter. 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 AC power adapter. In this mode, the hub is provided with 500 milliamps for all 7 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 AC adapter. When using the AC power adapter, make sure the plug is properly connected to the hub and to a standard electrical outlet. GE Surge protection is recommended.
