21.2.1 Output of device diagnostic information to a USB stick

To make it easier to analyze why a device is not connecting, you can output/save the device diagnostic infor-
mation locally to a USB stick.
1. Create an empty text file called "device.debug" and save the file ("Save as") to a USB stick.
You can use any simple text editor for this.
2. Insert the USB stick into the mbNET.
The mbNET writes the diagnostic information directly into the file ("device.debug").
During the write process, the mbNET status LED flashes green.
The USB stick must not be removed while the status LED is flashing.
When the status LED has stopped flashing, the USB stick can be removed and the file can be read from
the USB stick.
