My Dynon HDX (latest SW version 16.7.0 has been installed) just started to give me the warning that the BU Battery needs to be tested (I did it about 6 months ago and it passed). Problem is that when I pressed the Test Battery button (did this several times) the Dynon just rebooted and gave me a "System Event 3" message and told me to export the Diagnostic File to a USB. But the Dynon is not seeing that I have plugged in the USB (yes it is properly formatted as I checked the same USB in my other Display it works) to download the file. Any recommendations?
