Then I ran the STL11000 and nothing happened. No drop out at all. Roof opening and shutting with no issues. This confirmed it had to be the camera and its USB connection.
I then replaced the MHP with my spare and this did the same thing with both cameras ie QSI dropping out and STL11000 not dropping out. Now I knew it must be the MHP not being able to supply enough power to its USB's or to power the camera.
So I remove the QSI from the MHP and provide the QSI with its own power and USB. It works without drop out. All the other gear is still connected to the MHP. Nothing drops out.
So it appears that I need to take all the scopes off the mount and put in another USB cable through the mount and provide power in the same manner to power the camera. Further testing will identify any further issues. So it seems that in the end it is the regulated power supply suffering from a slight voltage drop when the roof opens and this affects the power to the MHP and that in turn affects the camera and forces it to drop out.
Anything else I should check?

glad you found it - i really consider the powered USB hubs as only an extension to get the USB past a few meters of cable extension. still recommend running two
