All USB devices go to sleep in idle mode on Windows 7

Question

A strange thing happened after a few updates to the system:

• Intel rapid storage
• SSD firmware update
• Intel Ethernet adapter update
• GPU Intel update

When the computer turns off the screen (after five minutes), an unknown time later, all the USB devices stop working.

• Sound card
• Mouse
• Keybord
• etc.

I can't turn them back on, so I can't wake up the screen or do anything except turn the computer off and back on.

I checked my power save profile and all is OK there. I changed in Device Manager, the Allow USB to sleep in all the hubs.

How can I fix this?

Answer 1

You could try looking at Control Panel > Power Options, then go to Change Power Settings > Change Advanced Power Settings > Usb Settings > Usb Selective Suspend Settings, and set it to Disabled? That looks like another setting that could allow the computer to suspend usb devices.
