Comment 21 for bug 990870

I have similar issues with a Logitech DiNovo (unified keyboard/mouse with proprietory bluetooth dongle).

I can't say for certain when the problem started but it is persistent on my current version of Ubuntu 3.2.0-32-generic-pae. I have a dual boot install (with Vista) and the Logitech Keyboard does not work at boot to select grub menu options so machine continues to default Ubuntu login. Keyboard does not work for Ubuntu login so I use a backup wirelees PS2 keyboard.

Sometimes after login the Logitech keyboard and mouse will function but only for a while. Eventually the keyboard and/or mousepad appear to lock up. Sometimes they will free themselves after a few minutes, Sometime they will free themselves after I power down/up the keyboard. Sometimes nothing works including backup PS2 wireless keyboard and mouse) and I have to reboot the machine.

I have tried many 'fixes' over the last month or two to no avail, including reinstalling bluetooth apps, setting KERNEL == 'hidraw*' in /lib/udev/rules.d/97-bluetooth-hid2hci.rules (http://ubuntuforums.org/showthread.php?t=1858493) and purchased a cheap usb bluetooth dongle to replace the Logitech one.

As I write this using USB wireless PS2 keyboard the Logitech mousepad works but the keyboard shows no response.

Strangely I just found KERNEL == "hiddev*" maybe I set it back at some point, so I will try it again and will report if it solves the problem.
