I am using my own custom board (www.olimex.com
). Do I need to check other settings on stack ? - I switch to PIC87j60 CPU (comment pic18f4550, but I'm using PIC16f67j50). For windows driver I try with "mchpcdc.inf" which is providing by Microchip (don't change anything) it is placed at "C:\MCHPFSUSB\fw\Cdc\inf\win2k_winxp_winvista32"
