With PLX's NET2280 and UDev, any Windows platform instantly becomes a USB device of your choosing. Precompiled driver software includes ready-to-run network and file system support, or you can implement a protocol of your own design. PLX's kernel-mode chip driver, called UDev, exposes a universal, well-documented API. The API enables every USB configuration imaginable. Fast-track your development by leveraging on a variety of working 'starter' clients and comprehensive source files provided in UDev's development kit. Need technical help? UDev's built-in branch-level recording feature allows you to share UDev trace logs with PLX engineering for expert technical assistance.
Applications:
Mass Storage - turn your Windows PC into a USB Mass Storage drive for file sharing!
Networking (RNDIS or Private) - Network your PC with other PCs over a USB cable!
Transfer - Starter example for learning and developing your own transfer protocol
Loopback - Engineering stress test
Platform Requirements:
Windows 2K, XP, or Vista

Welcome to PLX's UDev Help System! Our interactive help system helps you, the developer, quickly research PLX’s UDev Driver Library.
An Overview of UDev
UDev is a Windows export library driver for managing PLX NET 2280 silicon. PLX customers develop UDev clients on top of the UDev library. Developers do not need any knowledge of how the chip, chip registers, interrupts, nor (optionally) DMA1 works. They can therefore focus on results. Example client applications are available as starter models.
Along with the UDev driver, PLX provides working real-world client applications with sources. From established class applications such as USB Mass Storage and RNDIS, to vendor-specific applications such as Transfer (used as the foundation for most USB device applications) and Loopback (for engineering stress tests), PLX offers solutions for every requirement. New applications are added “on-demand.”
Getting Results
With UDev, the customer does not need to know intimate details of the PLX USB chip nor its operation; instead, the customer simply adds minimal platform-specific changes so that register access, interrupts and DMA1 work. The customer then chooses the most appropriate UDev client from PLX’s growing list of client applications, such as Mass Storage, Networking, and other engineering examples.
With a good hardware design and an appropriate “starter” client application, customers enjoy rapid deployment of reliable and efficient USB devices.
UDev Documentation Sections
PLX UDev documentation is separated into the following sections:
Client Functions: UDev exposes device and endpoint functions for client application use.
States and Events: UDev maintains device states, endpoint states, and uses event callback functions to notify clients.
Structures: Most calls to UDev pass references to structures.
