Issue:
Missing APC UPS device drivers.

A USB driver for communications between the APC UPS and Windows OS is pre-installed in Windows OS. The drivers should load automatically once the APC UPS has been connected to the computer using the proper USB cable. If the driver does not load, please review Video: How to verify USB communications between UPS and Windows OS using UsbDeview.exe.

NOTE: The PowerChute APC UPS driver is bundled with the PowerChute installer. The APC UPS driver will be available when PowerChute has been installed. If the APC UPS driver is unavailable, run the PowerChute installer with a UPS connected via USB to install the driver.
Or, download the attached ApcUpsUsbDriver.zip. Uncompress the zip and follow the instructions provided in the Readme.pdf.

8. Select APC UPS or APC Battery BackUPS from the list of drivers.

For Azure and Core user's to check the driver use pnputil.exe in PowerShell or the Command Prompt. See Microsoft Ignite linked article for instruction on using pnputil.exe. https://learn.microsoft.com/en-us/windows-hardware/drivers/devtest/pnputil-examples
