In the most recent patch version 1140773 released on May 4th for Hogwarts Legacy they have added full Dualsense support to the PC version.
Topic on Controller talk:DualSense
The controller articles are not locked to anyone, so you should be able to add info about that to the articles.
I would be happy to and tried earlier but it seems to be locked to me. I haven't edited a wiki page before but looking at the guide it said if I can't edit a page it will say "View Source" instead which it does. When I click View Source it says "You do not have permission to edit pages in the Controller namespace." above the text window.
Try editing other articles 3 to 5 times (I'm not encouraging vandalism though) and wait for 6 hours since account creation first before trying to to edit the controller article again.
Talking to the talk page also counts toward the edit counts.
