Try disabling autosuspend of the btusb module. That helped in my case.

To do that create a .conf file in modprobe.d

# cat /etc/modprobe.d/disable_autosuspend.conf

options btusb enable_autosuspend=n

reboot

check if parameter is set correctly

# systool -v -m btusb | grep autosuspend

    enable_autosuspend  = "N"
