Alright, yeah I had some issues with hiding it as well. Here's the reddit page I used that helped me figure it out:

Specifically, this quote:
I found his link for electrobrains' program was not working, so did a quick google search and the thread with the program is:

Just scroll down a bit and you'll see the download list. I used DS4Windows 1.0 Beta 10 2014 04 27.
After downloading it and opening it, it looks identical to InhexSTER's DS4Tool... Which may be what GoaLitiuM was referring to when he was talking about a patch, I'm not sure because there was no patching and I didn't have to alter any files as patches normally do.
I went ahead and tried it out. Here are the steps I used.
1) Download electrobrains' file.
2) Close Steam/Dark Souls 2.
3) Run DS4Windows program, connect my controller, Hide DS4 selected.
4) Start Steam, then start Dark Souls 2
5) Play.
I'm honestly not sure why electrobrains' program works for me whereas InhexSTER's doesn't, but I haven't had any issues at all since downloading it.
Of note are a couple of things:
1) I haven't opened up InhexSTER's DS4Tool since using electrobrains' DS4Windows program.
2) DS4Tool *was* working for me before using DS4Windows. I remember the specific moment I couldn't use my DS4 in Dark Souls 2 anymore, and that was when I accidentally went to Key Bindings from the menu, while in-game. At that point my controller wouldn't respond and I could only use kb+m.
I uninstalled drivers, removed and reinstalled bluetooth adapters, etc etc. No avail. Then I found electrobrains' program and it works like a charm.
Hope this helps man. And anyone else that may be suffering from controller issues.
