I want my USB keyboard to wake up my Windows 7 computer. I went into Device Manager, found the USB root hub, and under the 'power management' tab, the "Allow this device to wake the computer" is greyed out and unselectable.

So how do I allow my USB device to wake up my computer?

I have not tried through that route. I think you must go to each usb device in turn and apply the option (mouse: keyboard etc)

There are no power management options for the specific mouse/keyboard drivers.

In Device Manager, as I am sure you found, there are several USB Root Hubs,
You may be able to identify which hub the mouse and keyboard are connected to from the Power tab; then you only need to enable that one hub, and can let the PC turn off the others. But have you tried any of the others?

I have been able to identify which HUB my devices are plugged into, but, like I said in the OP:

There are a few things to check. Biggest one is to go to your Device Manager and look under "Keyboards". Right-click the keyboard itself and select the power management tab. It will give you an option here to allow the device to wake the system.

If this setting is ALSO grayed out, then make sure the sleep/suspend settings in the BIOS are enabled. Most often these can be found in the Power Management Setup area. There is also a setting here to allow the keyboard to wake up the PC, this must be enabled as well.

There are a few more things it could be but the above two should do it for ya.
