Windows 7: Keeping a setting in Device Manager

Keeping a setting in Device Manager

I have a Toshiba external hard drive which is externally powered and attached to the computer with a usb cable. I read on the web that the problem may be caused by Windows 7 conserving energy and shutting off external devices that are not in use.
I went to the control panel, opened Device Manager, opened the USB Root Hub and cleared the checkmark from Allow the computer to turn off this device to save power. Clicked OK and did the same for the other USB hubs.

However, if I go back to the Device Manager a short time later all the boxes are checked again! How do I make this setting stick??

Try going to the device itself in Device Manager, and telling it to Allow the computer to turn it off.

What problem are you referring to?

I'd agree with J_K, this needs to be done through Device Manager. If that doesn't work, could be the Bus Controllers.

1) Open Device Manager

2) In Device Manager, expand the Universal Serial Bus controllers list, right click on the Host Controller, click Uninstall and click OK.

3) Repeat step 2 to uninstall all items under Universal Serial Bus controllers.

Reboot the PC and Windows 7 will reinstall the controllers. A Guy
