It won't work fyi (I already reformatted once), the problem is the game itself. I have the issue on my laptop, not my older desktop. If device manager refreshes the game will take your controls from you for 2 seconds as it polls all of the hardware changes. The only fixes are Square Enix changing their code, or the other fix which is the only other practical one, I can only allude to.
No other game has this issue, when I realized it was localized to "only" FFXIV then suddenly it became easier to narrow it down. The community has "fixed" it but SE will only copy paste scripted responses in the tech forum. They will not fix it.
