Hi guys, I'm using a Logitech MX 518 mouse. It was working fine with the exception of the two side buttons; they weren't set up the way I liked and the mouse control panel did not let me change them. I installed some Logitech drivers (lcc213) that were supposed to support the mouse; upon reinstalling the mouse was not recognized by the Logitech software. The scroll wheel became very sluggish (maybe scrolling one line, and seemingly no acceleration). I removed the Logitech software and restarted, but now my mouse is stuck that way - moving the scroll speed in the Mouse preferences all the way to the left or all the way to the right makes no difference. Is there any way to reset the mouse drivers or whatever might be messed up, short of a reinstall? I even tried to use USB Overdrive and that likewise has no effect on the scroll speed. Gahhh. Should have left well enough alone.
