USB devices lost after PC sleep

[Omron Forums Support]

USB ports go completely dead in sleep mode which disconnects camera.

There is a way to keep the USB ports active during sleep mode.

1. Go into Device Manager, navigate down to Universal Serial Bus controllers.
2. On each USB Root Hub item, right-click and choose Properties. 
3. Click on the Power Management tab and un-check the box for Allow the computer to turn off this device to save power.
