Hi!

Not sure this helps but here's my experiences:

I have 2 QHY cameras and have occasionally had similar issues. For one of them, the issue seemed to be solved by having a separate USB cable from the camera - not running it through any USB hub (I have a powered USB 3-hub for focuser, filter wheel, and guide cam). For the other one, swithchg USB cables and hub seemed to solve the issue.

Moreover, at times my QHY 268m simply hangs and does not respond. I disconnect both USB and power, and reconnect, and it works again. This is typically when starting up, and then it will work the whole night.
