dymoprint: LabelManager PC "ValueError: The device has no langid"

I’ve been following the project hoping my old labelmanager PC will be supported one day and I was lucky #83 - now I’m trying to get it working, but it doesn’t. I can’t tell for sure if the device is working anymore at all since I don’t have any windows xp around anymore and at the last windows system in this house (W10) it’s just toggling connected/disconnected all the time but I guess due to different driver architecture nowadays.

dymoprint 2.2.1.post1.dev20+g0a33ed7

RuntimeError: 

You do not have sufficient access to the device. You probably want to add the a udev rule in /etc/udev/rules.d with the following command:

  echo 'ACTION=="add", SUBSYSTEMS=="usb", ATTRS{idVendor}=="0922", ATTRS{idProduct}=="0011", MODE="0666"' | sudo tee /etc/udev/rules.d/91-dymo-11.rules

Next refresh udev with:

  sudo udevadm control --reload-rules
  sudo udevadm trigger --attr-match=idVendor="0922"

Finally, turn your device off and back on again to activate the new permissions.

If this still does not resolve the problem, you might need to reboot. In case rebooting is necessary, please report this at <https://github.com/computerlyrik/dymoprint/pull/56>. We are still trying to figure out a simple procedure which works for everyone. In case you still cannot connect, or if you have any information or ideas, please post them at that link.

Permissions should be alright since

silverstar@Utopia-Planitia:~$ cat /etc/udev/rules.d/50-dymo-11.rules
ACTION=="add", SUBSYSTEMS=="usb", ATTRS{idVendor}=="0922", ATTRS{idProduct}=="0011", MODE="0666", GROUP="users"

and

silverstar@Utopia-Planitia:~$ groups $USER
silverstar : silverstar adm tty lp dialout cdrom sudo dip plugdev users lpadmin sambashare vboxusers libvirt

udevadm commands are done as given, plug out/in, logout/login, reboot, …
