I also have the same issues. I just purchased 7 ME-1’s and none of them will recognize the USB stick(s). It will either start and then crash until i cycle power or switch to a key flash mode without triggering an action to save the config to the USB. I have tried old 2GB and new 16 & 32GB formated for FAT32 with nothing on them. I really can’t believe this is still a problem since these theads started in 2013. So far I have not been able to transfer my default config to the other units. Very frustrating!.
