USB Dongle crash oeserver (core dump) on Linux OpenSUSE 42.3

[dominig]

While I can get (with some hitches) the Dongle to work on OpenSUSE 15.0, I fail systematically under OpenSUSE 42.3 (see Screenshot)

I did not find any missing lib with ldd with oeserverd.
Dongle is well detected by Linux.
The Journal indicates that oeserverd core dumped. As this is a closed code, I cannot do much.
oeservered works fine when the Dongle is not present and give me access to my chart set which is linked to my finger print.

Any clue how to debug that issue which is specific to that release of OpenSUSE and so linked to the environment ?

We had some problems in the flatpak build related to the libusb version. You might want to check by using the binary from the flatpak/ dir installed in ~/.local/lib or ~/.local/lib/opencpn.

Edit: Although bleeding edge, if oesenc is the only plugin you need you might also want to try the flatpak build. See for example OpenCPN/OpenCPN#1729
