Introdu tion
Overview
Universal Serial Bus (USB) port technology has emerged in response to the increasing number
of external peripheral devices (printers, scanners, modems, digital cameras, removable drives,
etc.) that are increasingly being connected to the latest generation of computers. The USB
behaves in a similar fashion to conventional bus ports (that is, serial, parallel, PS/2®); however,
since it does not require any IRQs, more devices can be attached to the system and the problem
of IRQ conflict is eliminated.
Since many older computers don’t have USB connectors onboard and most newer computers
come with only one or two USB ports, USB hubs are used to connect all the USB peripherals
that you may want to use.
The USB 2.0 (4-Port) Hub complies with the USB 2.0 standard. This represents the second USB
generation and provides transfer rates of up to 480 Mbps. It is faster, more efficient, and more
capable than its predecessor, USB 1.1; luckily, it is fully backward compatible, so your prior
investment in USB 1.1 peripherals is not lost.
The USB 2.0 (4-Port) Hub provides one upstream port and four downstream ports. LED indica-
tors display information about the power status of each port. The hub supports high-speed
(480-Mbps), full-speed (12-Mbps), and low-speed (1.5-Mbps) devices, and it can be daisy-
chained to provide as many ports as you require.
When you purchased the USB 2.0 (4-Port) Hub, you should have received:
• The USB 2.0 (4-Port) Hub,
• (1) 3-ft. (0.9-m) USB 2.0 cable,
• A power adapter, and
• This user’s manual.
Features
• ully compliant with the USB 2.0 specification.
• Backward compatible with USB 1.1.
• Supports transfer rates of 1.5, 12, and 480 Mbps.
• our independent, fully functional, 480-Mbps downstream ports.
• Per-port overcurrent protection.
• Per-port bus status LED indicators.
System Requirements
• One of the following operating systems: Windows XP; Windows®2000; Windows Me;
Win98 SE; Mac®OS 8.6 or higher.
• USB 2.0 Host Controller, installed on the computer.
NOTE
Only systems with a USB 2.0 driver installed can support data transfer speeds of up to
480 Mbps.
NOTE
The USB 2.0 (4-Port) Hub can be connected to a USB 1.1 Host Controller; however, it will only
support USB 1.1 speeds (1.5 or 12 Mbps).
Installation
1. Plug the supplied power adapter into an AC source. Plug the power adapter
cable into the hub’s power jack.
2. Plug the USB cable’s B connector end into the root (upstream) port located
on the hub’s side panel. (See the illustration.)
3. Plug the USB cable’s A connector end into your computer system’s USB host controller port.
4. To connect up to four peripherals, use additional USB cables. Plug each cable’s A connector
end into the downsteam ports on the hub. Plug the cables’ B connectors into the peripherals.
