Using libusb-1.0 with Qt (MinGW) in Windows 8

[Radek]

... moreover, libusb is a C library. I include in my C++ code (Debian here! Patch to your Windows!):

extern "C"
{
  #include <libusb-1.0/libusb.h>
}

extern "C"
{
  #include <libusb-1.0/libusb.h>
}

To copy to clipboard, switch view to plain text mode 

most likely, replace "libusb-1.0" with "libusb-1.0.20" and remove the INCLUDEPATH addition. Moreover, in Debian, accessing a USB device needs root privileges so that bye bye debugger.
