Have you tried the serial connection?

1) Apparently, this UPS needs to be told only to reply to specific
requests and not send unsollicited status updates. The bcmxcp (serial)
driver supposedly does this, the bcmxcp_usb (USB) doesn't. However, the
UPS remembers the last status, so this might help.

2) We want to be sure that the problem is not in the UPS.

Best regards, Arjen
