  • Welcome to AskUbuntu, unfortunately Windows is off-topic please see help center I would suggest moving your question to (superuser.com) – DnrDevil Jan 16 '16 at 14:42
  • @DnrDevil Why is it off-topic? I think he tries to create a Windows bootable USB using Ubuntu. – kalpetros Jan 16 '16 at 14:45

WinUSB functions require Windows XP or later. You can use these functions in your C/C++ application to communicate with your USB device. Microsoft does not provide a managed API for WinUSB.
