            Bug ID: 106391
           Summary: Intel 7265 BT on NUC5i3RYH constantly disconnecting
                    from USB when trying to pair
           Product: Drivers
           Version: 2.5
    Kernel Version: 4.3.0-997-generic #201510110154
          Hardware: Intel
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: high
          Priority: P1
         Component: Bluetooth
          Assignee: linux-bluetooth@vger.kernel.org
          Reporter: ernstp@gmail.com
        Regression: No

This keeps happening when I'm trying to pair a PlayStation 3 controller to my
NUC:

It works fine on another system with BlueZ 5.35.
I have played around with a lot of settings, like disabling xhci, disabling
wifi.
Tried many different kernels.

Not sure about the firmwares though?

Not sure if I have a D0 or D1? And I don't understand how the firmware loading
works...
It says 11003110e like a D0 but patchlevel 9 like a D1?

Aw, a forum post actually led me straight here, it's some kind of electrical
problem with the NUC!!

https://communities.intel.com/message/310705#310705

"You're not gonna believe this... but I managed to get mine working by shutting
it down.. then pulling the power from the NUC for a minute. That was it.,
Then it just started working. Seriously. Good luck you might get the same
result."

Worked for me too. Hope more people with the same problem will find this!
