Hi, I have 2 probes that are connected but shown as offline even after several power cycles. I performed USB stick troubleshooting procedures by removing the USB stick and saw NO-USB SOS message. But after inserting the USB stick there wasn't any new SOS messages. Plugged the USB stick to computer and saw corrupted file system. Formatted the stick and inserted it back, still no SOS messages. What kind of filesystem layout is expected on the stick? From what I read the probe should automatically partition/format the stick. Maybe the stick is bad. I do see a good amount of packet loss between the probe's network and the registration server. How robust is the firmware download process (e.g does it abort on TCP RST)? Is there any way to manually load the firmware? Thanks. Yang
