My Meteobridge TL-MR3020 cannot connect to my Davis Vantage Pro2 datalogger on my Davis console.

Looking at the log this is what is occurring:
logger (05.12.2023 10:35:26): data logger (version 5.4, build 15131) started.
logger (05.12.2023 10:35:27): station 0 (Vantage), can't open device /dev/ttyMH: No such file or directory
logger (05.12.2023 10:35:27): station 0 (Vantage), connect to station failed.
logger (05.12.2023 10:35:30): waiting for sensors (wind0, rain0, th0, thb0) to provide data.
logger (05.12.2023 10:35:30): services paused.

I have tried powering down AC power and batteries from the console. Disconnected the datalogger. Waited a minute and started up the console again. Before hooking it via usb to the meteobridge, I powered down the meteobridge, connected the usb hub to the meteobridge and powered back on. Unfortunately it did not work. This all started when I set up a new router and powered down the meteobridge, then restarting it after the new network was online. It always worked flawlessly for the last few years. Any help is welcome.

Do you use the mandatory USB 2.0 hub?

Yes, I use the mandatory USB hub.

However, the USB logger is not recognized by Meteobridge. Please check connections etc.

I checked all connections again and everything is fine as far the cabling goes and I also disconnected and reconnected everything from the data logger to the USB and then to the Meteobridge. I did notice on the information tab it says TL-MR3020 (no USB hub). Could it be that the USB hub is bad?

Problem solved after replacing the USB hub. Data is flowing to the web again. The old one must have gone bad somehow. Thanks for the help and suggestions.
