Comment # 1 on bug 910713 from Kenneth Ingham

I just checked, and the proposed fix in the Ubuntu bug report does not solve
the problem.

For reference, in case it is close to a real fix, I modified this file:
/usr/share/kde4/apps/bluedevilwizard/pin-code-database.xml

and added these two lines to it, near other lines for mice:
    <!-- Microsoft Sculpt Bluetooth mouse -->
    <device oui="28:18:78:" name="mouse" pin="0000"/>

It still requires that I connect to the mouse while the mouse is in pairing
mode to start working.
