I have problems to connect my dive computer and download dives from it to Subsurface.
I tried with the latest appimage.
with Debian :
vincent@ASUS-R558UV:~$ uname -a
Linux ASUS-R558UV 4.9.0-9-amd64 #1 SMP Debian 4.9.168-1+deb9u3 (2019-06-16) x86_64 GNU/Linux
Linux ASUS-R558UV 4.9.0-9-amd64 #1 SMP Debian 4.9.168-1+deb9u3 (2019-06-16) x86_64 GNU/Linux
When i try to download, i have the message :
Impossible d'ouvrir /dev/ttyUSB0 Scubapro (Aladin Square)
This is the content of the libdivecomputer log file :
Subsurface: v4.8.6, built with libdivecomputer v0.7.0-devel-Subsurface-NG (e4698c484461426a4cf4ef3fc1bdbb304b676f06)

Looks like you do not have permission to open the USB device to access the divecomputer. Try adding yourself to dialout group and relogin (documented in our user manual). Or for a quick test if this is indeed the problem, you could run sudo chmod 666 /dev/ttyUSB0 and try downloading again.

That's not going to work. The error message from subsurface ("Impossible
d'ouvrir /dev/ttyUSB0 Scubapro (Aladin Square)") is a bit misleading
here. The Aladin Square uses the USBHID transport. Whatever is entered
in the "device or mount point" (e.g. /dev/ttyUSB0) is not used.
You need to install the correct udev rules in the /etc/udev/rules.d/
directory. This one should do the trick for systems that use the plugdev
group (for example ubuntu):
