Yeah your right it is a battle!

Couple of things.,... I am finding that jumping straight into USB with these 18F chips may be a bit ambitious.

These 18F series do seem to be a bit more complex than your average 16F chips.

Just getting my head around the config fuses and using mpasm as opposed to using PBP Compilier is mind boggling but I think I got it.

At this stage I'm just trying to get the 18F to flash the LEDs and stuff LOL!

On another note, I tried to compile Mr E's usbdemo.pbp file and I get all soughts of errors. Any idea why? I mean the hex file works, but cant I compile his pbp file. I want to make sure that I can get the basics working first.

I tried tiny bootloader which apparantly supports 18F4550 chips but couldnt get it to work yet.
