I tested mine too with the latest release (4.5.4) and it seems to be working fine. Note that there hasn’t been any changes to the firmware since the stable release, so there’s no need to test the dev-firmware as it’s just the same as the stable one.
Update: I pressed on the connector and that made it stop working, with the same error on reset(). I then disconnected the sensor and reconnected it, then it started working again.
