Comment 25 for bug 550288

Hi@all

I was fighting the same problem after installing a fresh Ubuntu 10.04 LTS. First my Logitech bluetooth devices (MX5000 keyboard/MX1000 mouse) didn't work at all which was the reason why I stumbled upon this bug report. But the suggested workarounds didn't help me at all, because what I wanted to have is both working, the bluetooth dongle (thus switching to "HCI mode") and the mouse/keyboard (thus recognized as bluetooth devices). Changeing "hiddev" to "hidraw" or vice versa, commenting it out or any combination (e.g. mouse=hiddev, keyboard=hidraw and so on) mostly results in not switching the bluetooth dongle into HCI mode (hence remaining in HID mode) or doesn't change anything. Of course when the dongle is in HID mode the mouse and keyboard are working but I can't enjoy bluetooth functionality.

Then I discovered that it must have something to do with the pairing of the bluetooth devices because after replacing batteries in the MX5000 keyboard it connected properly (with passkey prompt) through ubuntu's bluetooth wizard. Since devices store the pairing status even after power off somehow in memory you have to "reset" them before trying to connect them with ubuntu. So the only thing I had to do is holding the tiny red button on the bottom side of the MX1000 mouse for a few seconds (same applies to the MX5000 keyboard) and voilà: it worked like a charm! It survived a cold reboot so I'm still happy. Hopefully the same will be effective for the other owners of logitech mice/keyboards.
