USB 2380, PCI Express to USB 2.0 Peripheral Controller
Standard PCI Express registers allow the existing Root
Complex to configure and send data to and from the USB
2380.
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

Express based Printer with USB 2380
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.

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.
