All credit for this one goes to @xudongzheng (thanks for helping debug
this!). Should fix the issue where keyboards go unresponsive after their
host machine wakes from sleep due to the USB driver entering an error
state. I was able to both reliably reproduce the issue before the patch
goes in and confirmed it no longer occurs post patch.
The `USB_DC_RESUME` state indicates the host event has resumed the connection.
Adding it to the list of valid connection states to prevent the error
when waking from sleep.
