Setting up the hub
1Make sure that no USB devices are connected to the hub.

2Plug the AC adapter into a power outlet or surge protector, then plug the DC connector into the DC power jack on the back of the hub.

Note: You can use the hub without the power supply when connecting low-power devices such as keyboards and mice.

3Plug the flat end of the provided USB device cable into the downstream port on your computer, or downstream port on another hub, then plug the mini-USB connector on the device cable into the upstream port on the back of the hub.

Windows detects the hub and installs the required driver. (The Windows Install New Hardware Wizard may prompt you to insert your Windows Installation CD to complete the driver installation.)

Notes:

•The hub must be connected to a USB 2.0-compliant computer or hub for it to function in high-speed mode (480 Mbps data rate). If the hub is connected to a USB 1.1- compliant computer or hub, it only operates in low-speed or full-speed mode (1.5 Mbps or 12 Mbps).

•High-speed hub drivers are included with most USB 2.0 PCI cards and are preinstalled along with the PCI card drivers. If you purchased an upgrade card prior to the release of high-speed hub support, check with your PCI card vendor for an updated USB 2.0 driver.

4Plug the USB A connector on the USB device, or on an additional hub, into any of the downstream ports of the hub. Note: When moving a device from one port on the hub to another, you may need to reinstall the USB drivers for that device.
