Here's the procedure I've had to use in Windows 10 and SGP. It allows me to control temperature (and see both temp and power levels) on a QHY247C. If I don;t follow this sequence, I basically have no control over or idea of what the cameras is doing for cooling.

- Power ON the QHY 247C
- Power ON the USB3 Hub
