Comment # 5 on bug 1092246 from Neil Rickert

>Where does this tool come from ? I can't find it in the regular repos...

  /usr/lib/udev/hid2hci

Part of the "bluez" package, version 5.49-2.1-x86_64 from vendor openSUSE

I'll note that I am not seeing the same problem in Leap 15.0 (on the same
computer) with "bluez" version 5.48-lp150.3.1-x86_64

Also, I am not actually using any bluetooth devices.
