Hi,

I just wanted to let you know that Cyberpower UT850EG is working, although it is not listed in the compatibility list. I am using WinUSB driver installed with zadig on Windows 10 Pro, and NUT binaries are obtained from NUT-for-Windows-x86_64-RELEASE-2.8.4.7z

UPS information : https://www.cyberpower.com/au/en/product/sku/ut850eg

UPS.conf, running with usbhid-ups -a cyberpower

[cyberpower]
    driver = usbhid-ups
    port = auto
    vendorid = 0764
    productid = 0501

Here is the upsc output.

Great to hear that it (both the Windows build, and the driver in particular) works for you, thanks for reporting!
