Standard PCI Express registers allow the existing Root

Complex to configure and send data to and from the USB

2380.

Firmware is available to configure the USB 2380 to

resemble a standard USB class device (like a printer or

mass storage device) for which no USB host drivers will

need to be written. For custom applications, firmware

APIs are provided to abstract the USB transactions to

reads and writes. This firmware is available for various

operating systems including Windows (XP, Vista, 7 and

CE), Linux, and VxWorks.

USB Duet Technology for Mobile PCs

The USB 2380 can be used to easily add a USB 2.0 client

port to a PCI Express based netbook architecture. The

hardware design is simple by connecting the PCI Express

signals to the PCI Express bus on the netbook chipset.

Adding a USB 2.0 client port to the netbook creates

innovative and killer applications for users, such as optical

disc drive sharing, instant file sharing, networking, and full

HDD/partition recovery, all over a simple USB cable

connection.

Software is already complete with Windows 7 Logo

certified and Linux drivers available for the USB Duet

file-sharing and networking functions. PLX provides a

turnkey hardware and software solution, which brings the

netbook with USB Duet Technology quick to market. For

Development Tools

PLX offers hardware and software tools to enable rapid

customer design activity. These tools consist of a hardware

module (USB2380EVK), hardware documentation

(available at www.plxtech.com), and a Software

Development Kit.

The USB2380EVK is a x1 PCI Express adapter board that

easily plugs into any standard PCI Express slot.

Both USB host and peripheral-side software is included

with the USB2380EVK. The host-side software consists

of USB drivers and test applications. The peripheral-side

firmware is used to configure the USB 2380 to resemble a

standard USB class device (like a printer or mass storage

device) for which no USB host drivers will need to be

written. For custom applications, firmware APIs are

provided to abstract the USB transactions to reads and

writes. While this software is available for various

operating systems, it is written in standard C with

portability in mind.
