ls -l would hve been better, It will show if this is a symlink and when yes to what and you are then able to do an ls -l of that device file and show it’s permissions. When not it will show permissions directly.
Also saying “when I try to connect/open device” is not very informative. You have to see these things from thje computers interpratation side. And the computer does not know any “I”. It does know loged in users. Also it is always much, much better to not say: “When I …, Then …”, show what you did and what the computer did. Copy/paste from the terminal into a post here. Like you did with those ls commands above.
