Got this working on my MAC pretty much straight away. Have spent hours trying to get it working on Windows. The instructions are not clear. Still have no idea what I should be doing to get libusb installed

When I cross compile for windows on my MAC I get lots of compile errors eg. undefined Milliamperes. Is the windows library different?

Yes, Windows is different. See https://github.com/google/gousb#notes-for-installation-on-windows. I don't think we'll provide any more support for Windows above that - you need to already be familiar with building POSIX-compatible code on Windows. The instructions for building libusb on Windows are by no means specific to gousb.

I managed to get this working on windows

For those stumbling across this issue the following worked for me

Windows 10 X64

  • Install msys2
  • run bash.exe
  • install either 32 bit pacman -S mingw-w64-i686-toolchain or 64 bit pacman -Sy mingw-w64-x86_64-toolchain
  • create /mingw64/lib/pkgconfig/libusb-1.0.pc
    (example below)
  • check version of libusb that installed
    pacman -Q | grep libusb
    $ mingw-w64-x86_64-libusb 1.0.23-1
  • create directory /mingw64/include/libusb-1.0
  • download correct version of libusb.h and extract to
    /mingw64/include/libusb-1.0/libusb.h
#lib-usb-1.0.pc
prefix=/mingw64
exec_prefix=${prefix}
libdir=${exec_prefix}/x86_64-w64-mingw32/lib
includedir=${prefix}/include
