Hi Darrel,

Yeah ive got a cap on the VUSB, same on both the breadboard and the project.
regulator? youve got me there!

Here is my config settings from my project, and I think it was from a thread about USB that I think maybe you had written (but dont quote me on that lol!)
It all works fine when its sat on the breadbaord, just not when its on my PCB.

Code:

                        ;              ;                      ; USB clock source comes from the 96 MHz PLL divided by 2
                        ;              ; [OSC1/OSC2 Src: /1][96 MHz PLL Src: /2]
                        ; No prescale (4 MHz oscillator input drives PLL directly)

Hope that helps.
