+        # does is to switch it to DFU mode and wait until it reconnects. This reconnection is
+        # never detected. But if we run the tool another time, the device list is queried again
+        # and opentitantool can finish the update. The device will now reboot in normal mode
+        # and work for the hyperdebug job.
