I create this post to share some findings.
Recently I experienced the issue of Polemaster losing frames and and freezing
Oddly enough I saw the same happening on my guide camera (ASI 120 Mini clone by Omegon)
The trick of playing video in background helped with the Polemaster but not with the guide camera
Just by google search I see I am not alone with those problems
I have this problem since a few months with my laptop (Lenovo X1 Carbon , Core I7 16GB RAM , devices connected to USB 3 Ports)
If I use my mini PC I never see the behaviour (same cables, same setup, same drivers, same Win10Pro version)
So I spent a couple of days testing , installing, reinstalling, using utilities in order to isolate the problem
in one of those tests I noticed that if you go to Device Manager and disable:
- Microsoft AC Adapter and
- Microsoft ACPI-Compliant Contro Method Battery
the camera starts to work better losing less frames (easy to check with ASI Studio)
I suspect some changes were made in the latest updates of Windows 10 in regard to USB2/3 and power management on laptops
Somehow Win10 understands its running on a laptop and manages the power on USB ports
Then I completely solved the problem with NO FRAMES LOST by connecting to a USB type C Hub
I conclude type C ports are managed differently in regards to power management in Win10 on laptops
Maybe somebody with better knowledge of Win10 may explain this behaviour or can find some setting to trick the laptop into thinking it is a desktop.
Hope this may help
