在開始安裝驅動程式之前，需要先下載除錯工具，讓驅動程式的Debug訊息可以顯示在除錯工具上面，目前最佳的Debug輸出訊息工具是DbgView，該公司目前已經被Microsoft併購，所以可以從Microsoft網站下載，下載完後執行DbgView並將Capture => Capture Kernel選項打勾，接著重啟DbgView


對於驅動程式的安裝工具，司徒目前使用NuMega公司製作的EzDriverInstaller，將main.sys和main.inf放在同一個目錄並執行EzDriverInstaller，選擇File => Open...(開啟main.inf檔案)，接著按Add New Device就可以在DbgView上面看到輸出訊息
