I have a CyberPower 850 UPS. For the last few weeks a message in the systray says a usb device not recognized. When I go into it vaguely mentions CyberPower. Now there's a message that ppped.exe has stopped. Looked it up and it refers to this again. Windows says that I have the most recent driver. Don't see anything at CP about this. Any cures for this?
