Hello, I modify MSVAD example in win7 RTM. The device name showed in device manager usually based on the information in .inf files. When i install several devices, they show up with a same name in device manager. During AddDevice or StartDevice, I can read the real name of the device, like "name 1", "name 2"... My question is, how can I update these real names in device manager? I have the DEVICE_OBJECT and the real name. Thanks! -- Danny
