I guess you are compiling under MS Windows ??? You probably don't link correctly to the USB lib. Try to compile the examples coming with libusb-1.0 to make you everything is right there.

I have tried redownloading a different version of libusb-1.0, but the problem was not solved.  What might I be doing wrong?
