USBDemo, something to learn USB a little bit

[Demon]

Pin 4 of the USB connector is Ground.
It and the Shield should be connected to VSS on the LAB-X1.
...

Tried both USB pin 4 (black wire) and the eyelet from the shielding connected to VSS, same garbles on LCD.

I used one of the VSS pins on the PIC, does it have to be a special VSS contact on the Lab X1?

...
Have you removed the MAX232 chip?
You've set the RX pin to output, which is likely to cause high currents if the MAX232 is still there.

I didn't remove the MAX232, but I installed headers on my Lab X1. The jumpers for RX and TX pins are disabled, same with VUSB pin.


EDIT: I didn't have the recommended capacitors so I used two 0.1uF ceramic caps in parallel across VUSB and VSS. Could that be a problem?
