Okay, it looks like I'm stuck with the 18F4550 for my USB projects. Nothing else seems to work for me. I'm trying to just compile this program with the Include "descript.bas", but it doesn't work. This descript file works just fine with the 18F4550. I checked the USB_DEV.ASM and USB_HID.ASM files, but I don't know what the problem is. It might be an easy fix, but this assembler language is not my best friend. Any help is appreciated. Thanks, Robert
