I have my Clip+ set in MTP mode. Usually it connects to my Kubuntu laptop correctly and I can view the playlists. But sometimes instead I get the messages "Could not read file" and "Could not lock the device" when I plug it in and try to view the Playlist folder.
I can clear the condition by logging out and logging back in again, but is there a less drastic way to clear the condition? I imagine there's a lock file somewhere -- but where?
