I don't consider it hijacking at all; you raise an appropriate question.
The Andonstar that you got seems to be intended for different uses from the device I got from BangGood.
My device is indeed recognized by Windows (as a "TIGA device"), and Windows finds a driver for it, but it is then barely functional as a Webcam, with a frame rate (at its 720x1080 setting, at least) of about 0.15 fps. Moreover, when it's connected to Windows, its screen shows only an unchanging USB logo, so images can be composed & focused only via the Windows screen. That feedback loop is slow to converge, to say the least. It reminds me of working in an old batch-process programming shop, or in an old wet-process darkroom. (Yes, I'm old.)
I will connect my device to Windows to recharge its battery from time to time, but probably I'll never try to use the connection for data transfer. I got the device because of its screen, so that I could use it as a freestanding scope. If I had a useful driver for it, I might use it differently.
