            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?
