Thanks for your inquiry. In order to see the status window information, TMT250 device has to be powered on. From your attached photo it seems that device is in charging mode, but not powered on.
Here you have two solutions:
1. Hold the power button till device turns on.
2. Set parameter "power on by USB/charger" value to "enable". Next time you attach an external power source to the device, it will automatically turn on.
