UPS: APC Smart-UPS 1500VA (SUA1500I)
Server OS: Windows Server 2008 R2 (x64)
Software: APC Powerchute Business Edition 9.01
Connectition type: USB

So after installing all the Powerchute software on the server the software would not pick up the UPS. All I got was “Device Communications: Not Established” even though it showed up in device manager.

When I installed the software I didn’t plug in the USB cable until it told me it was going to search for the UPS.

What I did to fix this:

1. I uninstalled any Powerchute software (agent, server, and console)
2. I went in to device manager and uninstalled the UPS also from under “Human Interface Devices” - I left the UPS plugged in, I did not unplug the USB cable
3. I reinstalled the Powerchute software and this time it just picked it up straight away

I hope that helps some one as Googling didn’t help me!
