That doesn't seem to work. My Pi Zero W /dev folder contains tty, tty0, tty1, tty2 etc up to tty63, but nothing starting ttyusb. There is a /dev/usb folder, but nothing there either.

This gives you the info regarding to connected devices and if they are correctly recognized.

Nothing is missing.... but it seems you are missing more specific driver for the station.
I've been doing some more checking, using weather station attached to a Pi 3B+ (which also has 4x USB ports).
Connecting the station to a different port gives an increasing Device Number in sudo lsusb as would be expected.
But CumulusMX 'just works' whatever I do. So I thought, it must be /dev/ttyUSB0 whatever I do (with nothing else USB plugged in.)
Then I fiddled experimentally with the CumulusMX / Settings / Station settings, which is where we enter /dev/ttyUSB0 [that's the defualt ... can change it].
I discovered . .. bizarrely ... that it makes no difference what I enter there. I can change it to another port such as /dev/ttyUSB1, or /dev/tty0 or even leave it blank. Saving that change makes the corresponding change in Cumulus.ini, BUT whatever I set it too CumulusMX just finds my weather station. It's like the program doesn't actually look at that setting.
