I'm trying to connect ny bluetooth keyboard, which worked fine until a recent update. After rebooting, I was able to type for a few seconds and then it stopped working. I unpaired my keyboard and now the bluetooth stack can't find it. I've tried scanning for other devices and they don't show up either. How can I troubleshoot this? I'm not finding any relevant errors in my syslog.
When running `hcitool scan`, I get this:
$ hcitool scan

Hello,
what is the output of :
hcitool devDid you try to restart the bluetooth service ?
sudo modprobe btusb
sudo systemctl restart bluetoothIf your are on a laptop you might have to active the bluetooth from the keyboard (fn+F12 for mine)

Hi, thanks for responding. I actually found out that I can scan for devices, but the problem is with pairing. I've started a new thread with my current problem here: https://bbs.archlinux.org/viewtopic.php?id=184560
So far I haven't been able to find any help -- I've tried mailing #bluez-users mailing list but I'm not sure if that list is active any more. I've also tried on irc in #bluez and #bluez-users, and on superuser.com.
