You like this and the official adb, adb is used AdbWinApi.dll AdbWinUsbApi.dll two dll function to do, but the premise is installed on your computer before you drive, the way is to get hold of the detection of pea pods Can not even look like on your phone, specifically how to use the two dll or to refer to the official document, or view source adb

Specific steps I could not say, but at least you're using MFC or C # software such as call AdbWinApi.dll AdbWinUsbApi.dll inside the function, the system comes with adb you need to install, adb is a use AdbWinApi.dll AdbWinUsbApi. dll application, you have to do is write an application, but you need AdbWinApi.dll AdbWinUsbApi.dll two dll, if you do not know MFC programming or C # programming, it is harder to resolve.
