btusb disconnect immediately after wakeup

[berenddeschouwer]

I've got a Realtek 8723be, wifi and bluetooth chip, and a bluetooth keyboard and mouse.

If I lock the screen (Fedora 22, gnome-shell), and unlock the screen, the bluetooth devices disconnect -- but only after unlocking.

gnome-shell powers down just about everything on lock. It's not a full suspend, but the screen and other devices are powered down. Dunno how to stop that.

So here's in more detail:

1. login
2. bluetooth is paired
3. lock (gnome-shell powers down)
4. unlock (type password using bluetooth keyboard)
5. wait a few seconds
6. keyboard and mouse disconnect

To fix: 7. rmmod btusb 8. modprobe btusb 9. stays connected until next lock.

While the disconnect is happening, you can see the devices constantly connecting and disconnecting, every two seconds or so.

Dunno if this is this driver, wifi driver, bluetooth or gnome-session problem, but I'm logging it here first because I'm using an out-of-kernel driver. The devices seem to work fine on another laptop.

from messages (journalctl):

I'm trying to find out if the following is immediately on lock. I'm pretty sure it's before unlock:
