Vista - Troubles with logitech bluetooth keyboard/mouse

Hi,

When I install vista on my computer, I can use my bluetooth keyboard and
mouse. When vista reboots my computer and I must enter my user-id for the
first time, my computer don't recognize my keyboard and my mouse. When I push
the connect button, I see on the display 'connected' but I can't typ
anything. Also my mouse is not working when I push the connect button. When I
restart my computer I can go into my bios without pusching the
connect-button. In my boot-menu I can also make a choise with my keyboard.
But when vista is started I can do nothing.

Please help me.
