Well, dang.

          // Current implementation force vbus detection as always present, causing device think it is always plugged into host.

          // Therefore it cannot detect disconnect event, mistaken it as suspend.

          // Note: won't work if change to 0 (for now)

          #define FORCE_VBUS_DETECT   1

I need to read up more on that… But that means that the “unplugged” event is never triggered which would cause it to go register as not connected again.

          // Disconnected

          dcd_event_bus_signal(0, DCD_EVENT_UNPLUGGED, true);
