I am using an Aardvark SPI to USB converter for a debug messaging 
capability with an LPC2114. I have developed a device with a USB 2.0 
interface and I needed a way to monitor the USB interrupt activity in 
real time to get through USB enumeration and configuration. My boss 
did not want to add a UART that would not be used in the final 
system.  The Aardvark connects to the LPC2114 with no additional 
chips. The Aardvark comes with an ActiveX interface and a DLL. I 
wrote a VB application that displays the activity messages and stores 
them to a data file for subsequent review. This has allowed me to 
develop the USB interface without a USB protocol analyzer (very 
expensive).  The Aardvark was developed by Total Phase 
(www.totalphase.com)
