UPS to Mac USB connection and hub
One tip (I think I read this here): if you have your UPS connected to your Mac via a powered USB hub, make sure that the USB hub is plugged into one of the battery backup sockets on the UPS. Otherwise, when the power fails, the hub will lose power and the UPS won't be able to shut your computer down.

Absolutely, I've seen this exact scenario more than once. Good way to screw yourself if you're not paying attention.

I was under the impression that most powered hubs, if the power is disconnected, simply revert to being unpowered ones. Certainly both of mine do. Since the UPS presumably isn't drawing any power from the USB tree, it ought to carry on working fine. |
