What chip are you actually trying to use?.
What compiler version?.
Only four of the DSPic's have a USB module. The 33EP256/512xx810/814. The module is the same unit as the PIC24EP.
On these chips the #define __PIC_24_USB_H__ is defined by the compiler, and the code does compile for these, but only with the latest compilers.
