Comment # 2 on bug 1183488 from Ulrich Windl

I have an update: I wa sable to pair the very same device with Leap 15.2
running on a different hardware, so the problem may be hardware (dongle)
specific, or driver specific.
Device that worked:
  Model: "Intel Bluetooth Device"
  Hotplug: USB
  Vendor: usb 0x8087 "Intel Corp."
  Device: usb 0x0029 
  Revision: "0.01"
  Driver: "btusb"
  Driver Modules: "btusb"
  Speed: 12 Mbps
