I am talking about the Cypress USB slave part, not the main PIC in the the
ICD2.  When you plug the ICD2 into a USB port, you get two drivers appearing
in the device manager one after the other. The first is the "Microchip MPLAB
ICD2 Firmware Loader", this unloads after a couple of seconds to be replaced
with "Microchip MPLAB ICD2 Firmware Client".  It was my understanding that
the first driver actually downloads the operating firmware into the Cypress
part.
