Comment 28 for bug 550288

In addition to my first post:

This morning I ran across another problem related to the Logitech MX5000-set: It seems that the bluetooth dongle doesn't get activated properly every boot up with the consequence of a not responding mouse/keyboard. Although the bluetooth indicator in the notification area shows up in deactivated/greyed out state it offers the option (by clicking on it) to deactivate bluetooth. If you do so nothing happens for the moment, but now you get finally the option to activate it, which properly works. At this point I was able you use my mouse/keyboard again (of course I did the activation with another non-bluetooth mouse).

Next time I booted up bluetooth was working from the beginning as it did in my first post... no clue what's happening here! But maybe this is the same misbehaviour which my previous speaker "lagerdalek" told about.

Cheers!
