Problem of transfer with vyper novo and ubuntu

[Yvan]

 Hello divers !

I have a Suunto vyper novo and I use Ubuntu. I cannot transfer the diving data from my diving computer.

In a terminal with the instruction sudo dmesg I found :

[132693.329599] usb 1-1: USB disconnect, device number 37

[132693.329622] usb 1-1.1: USB disconnect, device number 38

[132693.534137] usb 2-1: USB disconnect, device number 8

[132697.463559] usb 1-1: Detected FT232R

[132697.464568] usb 1-1: FTDI USB Serial Device converter now attached to ttyUSB0

Ubuntu seems to recognize my diving computer, but unfortunately in subsurface I have the error message :

Impossible d'ouvrir /dev/ttyUSB0 Suunto (Vyper Novo)

(I use a french version).

Couls you please help me ?

Thank you far all

I had a similar problem when trying to download dives from my Suunto Gekko, using Linux Mint 21.3 Cinnamon. The usb connection (Silicon Labs cp210x usb to uart bridge) seemed to recognised, with the lsusb command listing the device. Subsurface returned something like  [Error 13] could not open port /dev/ttyUSB0, Permission Denied when trying to download dives.

It turns out to be a permissions problem, as my distro (and probably others) doesn't automatically add the user to the relevant group.

Solved by running the following commands in the terminal

sudo usermod -a -G tty $USER 

sudo usermod -a -G dialout $USER

(although, if you hadn't already guessed, I'm a recent Linux noob, so I'm not sure which or both of these was necessary...it worked for me)
