Missing /dev/ttyUSB0

[Kari]

Hi

My problem might be a bit general Linux problem as Im missing the /dev/ttyUSB0 for downloading the dives.

After days of googling Im feeling that this is not going forward.

Help would be appreciated.

Kari :)

The Suunto EON Steel doesn't create a /dev/ttyUSBn - it's actually a HID
device, not a USB serial device. Subsurface simply connects to it
by its vendor and device ID. So in the UI we gray out the device portion.

Hi and thanks for reply.

On the newest version UI will gray out but but the error message still says

Insufficient privileges to open the device /dev/ttyS0 Suunto (EON Steel)

If I clear the device mount point and select some other device and back to Suunto steel
so that its grayed out again it gives different error

Insufficient privileges to open the device Suunto (EON Steel)

Im both cases dmesg gives a line

usb 8-1: usbfs: process 1913 (DownloadThread) did not claim interface 0 before use

This happens in 2 different Fedoras ..the windows version works without problems.
Sadly my laptop is linux :)

That's a permission problem which is covered in our FAQ https://subsurface-divelog.org/faq/

How do I fix permission errors when trying to download from my Suunto EON Steel under Linux?

By default new devices are sometimes given permissions that prevent a regular user from accessing them. If you get a permission error when trying to download from an EON Steel under Linux, please try these steps.

This should work on most Linux flavors. We’d appreciate feedback if this doesn’t work for you. Open a terminal window and cut and paste the following command. It may ask you to enter your password in order to allow access as super user (which is required to set up the udev rule that changes the device permissions as you plug in your EON Steel).

echo 'SUBSYSTEM=="usb",ATTR{idVendor}=="1493",ATTR{idProduct}=="0030", MODE="0666"' | sudo tee /etc/udev/rules.d/99-suunto.rules

If you disconnect and reconnect your DC it should now get the correct access permissions.

That should do the trick.

D,

what about doing that automatically from within subsurface (popping up a dialog explaining the error and asking to fix it, with a field for the user to put the admin password)?
