It seems to be at https://libusb.info/ I think you'll have to change  {$LINKLIB usb-1.0} into something like {$LINKLIB libusb-1.0} and libusb-1.0.dll and libusb-1.0.lib should be accessible on your path. Some unix libraries are available through distributions such MinGW (http://www.mingw.org/) It seems libusb is available under windows (libusb-1.0.22.7z) with four different compilations: -MinGW 32 bits (I imagine it uses the libc from mingw, the glibc I suppose) -MinGW 64 bits -MS32 I think it's compiled with Microsoft Visual Studio/ Microsoft Visual C++ and use the MSVCRT dll -MS64 the same in 64 bits architecture.
