From http://www-users.york.ac.uk/~mdc1/samsung.html#btmouse:
To get the Logitech V270 Bluetooth mouse to work was simple. As root in a terminal window type: hidd --server --search then push the reset button on the mouse and it will find it and pair. You can check by doing (as user): $ hidd --show xx:xx:xx:xx:xx:xx Logitech Bluetooth Mouse [046d:b002] connected Then you only need: chkconfig --level 35 hidd on From now on the mouse just pairs up after the system is booted by moving the mouse around until it responds.
The mouse is properly connected via bluetooth now. Unfortunately the mouse did not move yet.
One more step was missing (which was also on the named page - read before you weep). The X configuration (/etc/X11/xorg.conf needs to be edited.
