PowerChute agent loosing connection to SUA3000RMI2U

[FeYsT]

Good day. 

I have Windows server with Powerchute Business agent installed. It is connected to SUA3000RMI2U UPS through USB cable. 

Sometimes agent tells that it lost connection with UPS. I've watched to windows event logs and every time there was two entries (for example):

14:24:04 - 3000 - APCPBEAgent - "Lost Communication With UPS"

14:24:04 - 1002 - APCPBEAgent - "Communications Established"

This may happen several times a day, or once a week. I've tried to change the USB cable, but no luck.

Is there a way to resolve this communication issues? Nothing critical, but annoying.
