Worst day of my life

[brid0030]

So I tore down the breadboard and tested all the components. Found a capacitor marked at 10uF that only read off at 0.7uF. I replaced it and tried again. This time when I tried USBdemo, the PC recognized it as a USB CDC device and let me install the driver. BUT, I still could not get any communication between the Vbasic program and the PIC. Then I tried the CDC for dummies thing again (now with a 20 MHz crystal) and it worked just fine. So, I am off and running now. Too bad about USBdemo...would have been fun to play with.

Great, glad you found it. Kind of hard to find those things from this end.

If you have both the USBdemo and the CDC for dummies projects in the same folder, the files will conflict.
Since you tried CDC after HID failed, the files are probably still set up for CDC.

A fresh install of USBdemo in it's own folder would probably fix it.
