Then you can do whatever you want on both the PIC and PC side of things. You can also get pre-made USB modules that plug into a DIP socket, syou can even transfer them from PIC board to PIC board or use in a solderless protoboard (Ugh... these things should be outlawed for most uses, but that's another subject).
