Hi, i searched the forum to communicate with a logitech G600 without using Shortcuts or Default Mouse Keys. the code below lets u use your sidekeys whenever you press down the ring key. before using the code you will have to unassign the keys in the logitech mouse driver software. The source of my code is a wacom usb script, wich was heavily modified to work. you might find some parts wierd, thats because this is my first attempt to communicate via raw hid. #Region ;**** Directives created by AutoIt3Wrapper_GUI **** #AutoIt3Wrapper_Change2CUI=y #EndRegion ;**** Directives created by AutoIt3Wrapper_GUI **** #include <APISysConstants.au3> #include <GUIConstantsEx.au3> #include <StaticConstants.au3> #include <WinAPIGdi.au3> #include <WinAPIMisc.au3> #include <WinAPISys.au3> #include <WindowsConstants.au3> #cs ;
