Power Down USB devices on Full Shutdown?

To be honest I would perform a full shut down and reboot on the console (power down from the power settings in the settings menu, full shutdown). It shouldn't be doing this, more than likely a reboot will correct it.

Most of the time a full shutdown of the console or a simple restart will fix the issue if you leave your console set to instant on. Make sure to do a full shutdown by going to the settings tab then under the general tab click on power mode and start up....click
on full shutdown. If that doesnt work do a hard reset by holding power button in on the console until it powers down. If that doesnt work unplug the console for 30 seconds and restore power. This should correct most issues on the console. I hope this helps

Doing a full shutdown fixed it for me. When you use the xbox controller or the power button on the front of the xbox it goes to sleep/hybernation. Doing the full shutdown completely spins down the xbox operating system clearing all drivers from memory
and reloading them. This is a common problem with sleep/hybernation on all systems including xbox.

The fix:

Go to Settings > All Settings > Power and Start Up > Turn off or restart > "Full shutdown". Then power your xbox back on.

You have two choices

Shutdown- fully power down.

Sleep - standby mode

Both have full text descriptions in the menu.

You can do a full shutdown by going to settings and power and select full shut down. Or you can simply hold the power button down for 30 seconds and do a hard reset that way. I always prefer to do the full shut down though via the menu but either option
should assist you. Good luck!
