Look at the top of the file and you find the directive "PKGCONFIG += libusb-1.0". On OSX, this might have to be renamed to "usb-1.0" which you can add to line with the Mac-specific definitions, thus: mac:INCLUDEPATH += /opt/local/include PKGCONFIG += usb-1.0 I'm not sure, however, whether "usb-1.0" is correct in your case. Look into your folder which contains the package config files (*.pc) and you should be able to find the correct name. Adrian -- .''`.
