As you know been having pressure problems on my tablets for almost 2 years, i have two computrs a laptop and a desktop with windows 8.1 and inboth had same problem. The reason its because when you install your tablet and plug it, windows install his own drivers that clash with the wacom drivers, this happens all the time you plug the wacom, they are downloaded automatically. They are really old drivers from 2006.
So if you have the same files as i do as you can see on the image, the only way to stop them its disabling them. like i did on the image.
The important one its the pen one, if you disable the digitizer depending on the version of your tablet it can make it crash, but if your tablet its new model, lyou wont have a problem disabling the two, but the one that fixes the pressure its the hid-compliant pen
Dont worry, it wont crash your tablet, it will work fine, but now i can feel the 2048 levels of pressure. Some people pointed out they dont have the same files, it seems its reandom, ive havent found a pattern yet.
But if you have them, will be nice if you can tell us the tablet model and what windows version you have.
The way to see this files, its going to control panel , then device manager, then going to the HID section, open it and look for thse two trouble makers.
Help us to find a pattern to this.
