This is what made me ask the original question around the tty device.
Also my lack of understanding about the fact the watch is a HID device too.

I start the Subsurface appImage from the command line, this is the output I get.

$ /opt/bin/subsurface -v

That is it. Unless you need me to run Subsurface in a different way?
I can also go back to the libdivecomputer test tool directly after this and still get a successful connection.


Thanks for every ones time,
