Program Description:
-------------------

This application note covers the implementation of a simple USB application 
using the interrupt transfer type. Thisincludes support for device enumeration, 
control and interrupt transactions, and definitions of descriptor data. The
purpose of this software is to give a simple working example of an interrupt 
transfer application; it does not includesupport for multiple configurations, 
or other transfer types.

How To Test:
-----------

1) Download the code to any C8051F34x target board using the Silicon Labs IDE
2) Run the GUI application that comes with the firmware and test the features


Known Issues and Limitations:
----------------------------
	
1)  Firmware works with the Silicon Labs IDE v1.71 or later and the 
	Keil C51 tool chain. Project and code modifications will be 
	necessary for use with different tool chains.

2)  Compiler optimization emphasis is selected as "favor small code". 
	This selection is necessary for the project to be compiled with the 
	trial version of the Keil C51 Compiler (under 4k code space).

3)  If using the C8051F340TB target board, the VREGIN-VBUS pins should be 
        shorted if bus powered.  The VREGIN-VDD pins should be shorted
        if wall powered.

4)  Windows application and driver supports Win2K, XP, and 98SE only.
