Hello Marcel,

here we go,

BTW: does anybody know whether there is a special way to "activate" the 
mouse? Its red sensor LED was flashing until i did a "hcitool scan" for 
the first time. Now (even after removing / re-inserting the batteries) it 
shows no activity at all. Do i need to say that i would need "Win XP" to 
get to the "IntelliPoint" software that tells me more? There's not a lot 
of info in the printed "Getting started". I "love" the idea of changing to 
another "OS" version just because i want to use a more advanced 
keyboard/mouse. ;-)
