pic18f4550 & VB6 ... help meee!!

HI,
My name is Davide Longo and i'm an Italian university student.
My first experience with Pic has been use the PIC16C765 with usb interface and a Visual basic 6 software for elaborating data. In VB6 i used an additional component, HIDcomm.
Now I would like start to work with 18f family. My problem is that i don't understand which kind of firmwares i must use.
For the pic 16c765 i used:
usb_ch9.asm
hidclass.asm
descript.asm
usb_defs.inc
...

but for the new pic (18f4550) i don't find these kind of firmwares.
I read about EasyHID but i don't understand very well.

My question are: exist the analog firmware for the pic18f4550 in assembler ? and can I interface this pic with VB6 using HIDcomm?

Have you got a simple example for turn on a led by usb comunication to pic18f4550 and vb6?

Bye!
