Setting up the hub
1 Make sure that no USB devices are connected to the hub.
2 Plug 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.
3 Plug 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.
4 Plug 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.
