    That's funny.

    Very close,
    but no cigar.

    should be...
    Code:
       ; __CONFIG _CONFIG1L, _PLLDIV_5_1L & _CPUDIV_OSC1_PLL2_1L & _USBDIV_2_1L 
   ; __CONFIG _CONFIG1H, _FOSC_HSPLL_HS_1H 
   ; __CONFIG _CONFIG2H, _WDT_ON_2H & _WDTPS_512_2H 
   ; __CONFIG _CONFIG3H, _PBADEN_OFF_3H 
   ; __CONFIG _CONFIG4L, _LVP_OFF_4L & _XINST_OFF_4L

    I think Steve's original circuit was the same as the schematic at the bottom of the EasyHID page.

    http://www.mecanique.co.uk/products/usb/easyhid.html

    At least I don't remember him posting a different one.

    It could be that you are using PBP version 2.46 - 2.50C with MPLAB greater than 8.15a

    Either upgrade PBP, or downgrade MPLAB.

    If you have upgraded PBP, use the new USB files from the USB18 folder.
