Overview
Universal Serial Bus (USB) port technology has emerged in
response to the proliferation of external peripheral devices
(keyboards, mice, scanners, digital cameras, removable drives,
etc.), that are increasingly being connected to the latest generation
of PCs. The USB behaves in a similar fashion to conventional bus
ports (i.e., serial, parallel, PS/2), but is much faster, and since it
does not require any IRQs, more devices can be attached to the
system, and the problem of IRQ conflict is eliminated.
The PX-440C isa PC Card 2 port USB2.0 host. This credit card
sized host is the perfect way to add two USB 2.0 ports to
standard notebook PCs. Installation is quick and easy, simply
slide the PC card into the Type II CardBus slot on your
notebook, and you’re USB ready!
The PX-440C represents the second generation of USB
standards. USB 2.0 technology offers the advantages of
high-speed data throughput, (up to 480Mbps), chainability - the
ability to daisy chain up to 127 USB devices, "Plug and Play",
Hot-Swapping (connection and disconnection) on the fly, and
allows users to take advantage of the USB 2.0 technology on
their current USB 1.1 systems.
With USB 2.0, the latest high-speed peripherals can be connected
externally, eliminating the need to install complicated hardware.

Introduction
1. DC Input Jack
If you choose to use an optional DC Power Adapter (requires
separate purchase), its cable plugs in here
Note: Ordinarily, the hub gets its power from the computer,
but if large, or power hungry peripherals are
connected, this might not be sufficient, and may result
in erratic operation. In this case, a DC Power Adapter
should be used.
2. USB Type A Ports
The cables from your USB peripherals can plug into either
port.
