Hi,
Come on Robert :-)
He says that he's compiled the program with PBP3 and the posted error messages supports that statement saying PBPX version 3.0.7.1.

Unfortunately I don't know my way around the USB stuff so I'm not able to help with that except for suggesting to read thru the USB.TXT document in the \PBP3\USB18 folder and trying to compile the examples provided to start with.

Regarding the i would really like to know where do i configure my PIC18f2550 statement I suspect you mean the configuration fuses and if that's the case look at the #CONFIG / #ENDCONFIG directives in the manual.

/Henrik.
