How to keep USB power to UPS during sleep?
Hello:
Barely literate forum noob here; not sure if I am in the right forum for my query.
I have been wrestling w/this issue since Vista...
Issue:
Want to configure power settings for desktop PC so that USB power to UPS can be maintained during sleep.
The UPS software can do a managed system shutdown during a power outage only if the UPS can "communicate" with the computer. As I understand it, Vista and 7 cut power to USB ports during sleep, breaking that connection.
Is there a way to do this that won't screw up the other installed USB devices such as keyboard & mouse & monitor, or the use of external USB flash drives or hard drives?
What I've tried so far:
In Vista, my only good workaround was to devise a power plan that never put the computer to sleep (only the display turned off).
That's what I'm doing now on this new Win7 64-bit box, but I assume there's way to devise something more definitive and more energy-efficient.
Trouble is, I find all the options& settings confusing:
-- Device manager for the USB hub: "allow the computer to turn off..." and "allow the device to wake..."
-- Power settings: sleep vs. hybrid vs. hibernate; "USB selective suspend"; turn off HDD vs. turn off computer.
Secondarily: It seems that Win7 also cuts power to the Ethernet card during sleep, breaking the connection to the router. Is there a way to fix this, as well?
Assuming there is some sort of solution, can someone please provide step-by-step instructions suitable for an old fuddy-duddy, self-taught geezer?

I really appreciate your help.
