Hi beautiful people:
I have recently purchased a Dell U3014 monitor and I'm experiencing some bizarre behaviour.
The very moment I plug the USB3 cable to any USB3 port the unit powers on. If I try soft-off the unit shuts down then in a couple of seconds powers on again. The only way to shut the unit down is cut the power during those couple of seconds (via the switch on the PSU). If after this I switch the PSU on again most of the time the unit stays off.
This happens both in the "fixed" USB3 ports or on the ones on the MB headers (via appropriate bracket).
I have tried two monitors, five different USB3 cables (different as in different lengths and makes, not just five iterations of the same model) with the same outcome.
This however does not happen when I connect my 7 port USB3 hub (which I was hoping to retire).
I have also changed the xHCI mode on BIOS from "Smart Auto" to "Auto" but it has not made any difference.
Any suggestions on how to prevent this behaviour? (besides "don't plug the monitor's USB hub" that is )
BIOS version is F15r.
Thanks for reading :)
