Why does my USB device stop working after my computer wakes back up from sleep mode in Windows?

If the USB device does not work after your computer has been in extended hibernation, it is likely that Windows has automatically turned off the USB Root hub to save power. 

The steps below outline how to configure the USB root hub to stay on during hibernation, to prevent this from happening.
 

Windows 10 / 8

  1. On your keyboard, press the Windows key + X and select Control Panel.
  2. Click Hardware and Sound, then click Power Options.
  3. Click Change plan settings for the plan you want to change.
  4. Click Change advanced power settings.
  5. Click the plus sign (+) next to “USB settings” and “USB selective suspend setting” to expand the options and change the setting to Disabled.
  6. Click OK to apply the setting.

Note: You may need to disconnect and re-connect your USB device after applying these settings to re-establish the connection.

Windows 7 / Vista

  1. Click the Start button and select Control Panel.
  2. Click Hardware and Sound, then click Power Options.
  3. Click Change plan settings for the plan you want to change.
  4. Click Change advanced power settings.
  5. Click the plus sign (+) next to “USB settings” and “USB selective suspend setting” to expand the options and change the setting to Disabled.
  6. Click OK to apply the setting.

  4. Right-click the first USB Root Hub device and select Properties.
  5. Click the Power Management tab.
  6. Clear the box next to Allow the computer to turn off this device to save power.
  7. Click OK to apply the setting.
