When I installed DPNAssistant 1.4 the first time it worked with the latest (1.6) Oculus App. After reinstalling the DPNAssistant I couldn't get it working. Oh and I disabled the option in Antivir "Block registry modifications", so the registry can be changed. It has something to do with the registry.
I wasn't afk while installing software. I confirmed every single driver request!
I have 3 different USB types: USB 3.0 (blue), USB 2.0 (black) and USB ?? (red) on my MSI Z97 Gaming 5.

When you put the Deepoon into DK2 mode, you get that DP Assistant "error" where it says it's not connected (or at least I do) and the light is red, but it still works for me when I start Oculus Home (worked with 1.3, 1.4, 1.5 and I just tested 1.6 last night).
The only way I can get the light to go blue is by disabling the Oculus runtime and then putting the Deepoon into either DK1 mode or native Deepoon. Even with Oculus runtime disabled, if I put it into DK2 mode, the light goes red and DPA (1.2, 1.3, 1.32 and 1.4) stops recognizing it.
You don't even need DPA installed for it to work, only if you want to switch modes. I still have DPA installed though, since I need to go into DK1 mode to play Skyrim.
YMMV
