I'm also in the middle of trying to use EasyHID. I'm just not sure where the USB18.ASM file fits in the grand scheme of things.

I used the PIC18F4550, PBP and VB. The file is in the project PBP folder.

I also got USB Complete as well as USB Design By Example. It's too bad they chose to use EZ-USB chips from Cypress or else I could have used their examples directly. Unfortunately I don't know enough about MPASM Assembler, let alone Cypress' version to convert things around.
