Hi All, I have got the Belkin F6S600auUSB UPS working with the blazer_usb driver. I pulled the power to the ups last night and it sent a message to the server saying it was on battery then ran for another 10 minutes and then sent a message to the server telling it to shut down, which it did. upswr did not return anything.
