Yes, I've reported this problem already, but then it was decided,
that UPS is defective.
Now, I've checked with 3 different USB debugging tools on Windows 10
notebook, that it doesn't disconnect from Windows host.
And it flicker on FreeBSD systems.
Looks like, we need some quirk for this class of devices.
I could collect logs on FreeBSD and Windows, but I don't know what to
compare and where to look.
Is this the same like:
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=237666
I have this loop:

Could you try to install FreeBSD 11 and see if the issue goes away?
I could boot from some live media of FreeBSD 11 on same Laptop as I have
Windows 10 installed . I'll try it ASAP.
What does usbconfig say?
Can you enable host controller debugging:
hw.usb.xhci.debug=17
hw.usb.ehci.debug=17
hw.usb.uhci.debug=17
hw.usb.ohci.debug=17
--HPS
