Pic 18F2550 with bootloader setup issue

[Yves]

Hello,

I have a 18F2550 and a 8Mhz crystal on board. I think my config is not correct as I can't even flash a LED on portB.1. I use USB_BootLoader_Win64_V1.07A.exe to send the code without problem and I see it is connected on Dview program but no com port is shown. where I am wrong?

USBDIV = 2
VREGEN = On (*1)

*1 --> Minimum 1uF from VUSB to GND, unless you have the 18LF2550 and you power the PIC from 3.3v, actually it is best if you can show the USB part of your circuit and you mention the power voltages.
