Hi,

I'm having trouble with getting the Indi_vantage_weather driver connected with the Davis Console. I am using the USB Data Logger connector, which is plugged into a USB port on my observatory controller (Raspberry Pi running Ubuntu 20.04 LTS).

I'm attaching a screenshot that shows the error. I have tried the default port "/dev/vantage", as well as scanning the ports. Seems like the Pi is recognizing the USB device, but it keeps saying it is already being used by another device/driver.

I'm having a suspicion that it has to do with persistent port mapping, but I not very great with Ubuntu yet. Anyone have an idea what to check?

thanks!

Nobody else has a Davis weatherstation?

Did you check if /dev/vantage is pointing to the correct /dev/ttyUSB or /dev/ttyACM device that actually controls your Davis Console?

Yes, when I list /dev/vantage the symlink points to /dev/ttyUSB0. I have also confirmed that the udev symlink details for 99-vantage.rules are correct and match the device.

But I can't get a connection in the indi_vantage_weather driver using port /dev/ttyUSB0, /dev/vantage, or /dev/serial/by-id/usb-Silicon_Labs_CP2102_USB_to_UART_Bridge_Controller_0001-if00-porto (which is what shows up when I use the auto port scan option in the driver). Is it possible that the /dev/serial/by-id is interfering with the /dev/vantage symlink? Or what else could be causing the error that the port "is already used by another driver or process. "?

The " Do Not Use FTDI and Profilic Serial-USB Drivers in the Same Setup" topic (#76705) may provide you with useful information into solving your problem if you have more that 1 /dev/ttyUSB device as there are potential conflicts between FTDI and Prolific serial USB devices. I had such a conflict between my focuser and a non-existent vantage device and removing the /lib/udev/rules.d/99-vantage.rules solved my problem.

I'll let you know if I think of something else.

So I finally figured this out. There was a line in the udev GPSD rules file that was using the identical device as the /dev/vantage.
I commented it out and rebooted - success! Now I just need to figure out how to hook multiple weather stations into Ekos so that the observatory shuts down before everything gets wet...

I'm just going to link this thread here as well - same issue. Might help someone down the road indilib.org/forum/astroberry/6316-ttyusb...raspi4.html?start=48
