Comment # 6 on bug 1216799 from Silviu Marin-Caea

Finally, I got a laptop where I planned to install 15.0 to see if it works with
that. But I started from 15.5 to have a baseline where it doesn't work.

Except it did work. I could not reproduce it.

So I thought what could cause it on my desktop at home? Well, there is an USB
extension cord that I connected the dongle with. Turns out there are no
bluetooth disconnections if I plug the dongle directly into the PC.

I'm closing the bug as invalid, sorry about the wasted time.
