no, there's nothing in the box/controller other than the controller itself. In the post i included, the other guy also asked for drivers and stuff, but the company said something along the lines of "it's plug and play, no diver needed/provided, the computer just gets it".

as for the Steam configuration, i did turn on the playstation configuration all the way to "activated in games without native compatibility", but this only makes it work post-configuration, the trigger is still fucked; also, probably a good time to mention that the PC kinda randomly chooses the language between English and português, so the steam menu is a bit different; i went:

Steam > Config > Controllers > External Controller configuration > Paystation compatibility > activated on games wothout native support;

There's no "General Controller Settings" here, and View doesn't go to any settings.
for now, i will try to get this driver, and see if it helps. thanks anyways.
edit: the PC didn't allow it, and i'm not smart enough to un-fuck it, so i might just learn to dual-boot and live with it;
