Package: xserver-xorg-input-evdev Version: 1:1.0.0.5-2 Followup-For: Bug #365581 To the above poster: You can use the mx510 with the normal mouse driver. But I second his report, replugging the mouse is lost from X. At a point I thought it might have been udev assigning it to a different event file in /dev but even if using a persistent name, it would remain with the same behavior.
