Hi,

I have a program that works on a development board but does not work on the board I made. The 18F4550 works for the internal program but the USB portion does not work at all. I have checked the traces and verified everything is OK. I am confused about the VUSB pin and what capacitor values go on that pin. I change that value and the computer starts to recognize it but I can't find the correct value. Can anyone help me?

Thanks,

Chris
