Micrium announces uC/USB V1.00, a USB client bulk stack.
 
The USB client bulk stack has been designed to work on any embedded 
system with USB client controller. A hardware abstraction layer 
makes it possible to easily write or modify existing routines 
hardware access routines. It can be used with USB 1.1. or USB 2.0 
devices.
 
The stack consists of an embedded side, which is shipped in source-
code form, and a driver for the PC, which is typically shipped as 
executable (.sys), but is also available as source code.
 
The purpose of the USB stack is to allow developers to quickly and 
painlessly develop software for an embedded device to communicate 
with a PC via USB. The communication is like a single, high speed, 
reliable channel (Very similar to a TCP connection)
 
It basically allows the PC to send data to the embedded target, the 
embedded target to receive these bytes and reply with any number of 
bytes. The PC is the USB host, the target is the USB client. The USB 
standard defines 4 types of communication: Control, isochronous, 
interrupt and bulk. Experience has shows, that for most embedded 
devices bulk mode is the communication mode of choice. It allows 
usage of the full bandwidth of the USB bus.
 
 
Speed:
  The highest possible transfer rate on USB 1.1 (12 Mbit/sec) 
devices is app. 1.1 MByte per second. This data rate can indeed be 
achieved on fast system, such as ARM7.
 
What is included (depneding on the licensing choices):
  Sources of the stack (target side)
  Sample config
  Sample hardware layer routines
  PC-Programs (in source and exe form) to help bring up and test the 
system USB driver and .inf file.
