I just uncommented the 24Meg option in UsbInitialize and commented out the 40Meg option. Look at the comments and you will see it, the PLL enable stuff.

I think you need to change the value in upsd_hardware.h to match as well since it's set to 40MHz too! Anyway, that worked for me. As soon as I downloaded the updated hex file(s) it enumerated automatically. I didn't even hit RUN yet (so there is some setting I need to look at -- I don't use the Keil debugger normally so it's all Greek to me).

Also I had made separate directories for LST and OBJ (as is my habit but not how this project was done), and I found I hand to manually place the HEX file back into the project root prior to loading so there is a path set somewhere. Another setting I have to find...

The web pages stored on the USB Key are different now too.
