Hi,
there are no useful messages.

Oops, yes, with root privileges the traytoggle option works for opening
and closing, but without root privileges the user can only open the tray
by using 'eject' without the toggle option.
There's an udev rule from end of last month, maybe it stopped already
working in the end of last month.
I don't understand the content of the udev rule, but as soon as I've got
more time, I'll take a look, if the rule did look different before.
