  It works (with sysutils/nut) when it is connected, but flickers!

  Is here any way to be sure, that this is UPS problem and not FreeBSD one?

  I'm running


Hi,

Try dumping the traffic using "usbdump -i usbus1 -f 2 " and look for completion errors. Might be a bug in the USB firmware of the UPS.
