I want to take this moment to welcome you to VectorLinux. I hope that your experiences here with VL and the community will be an end to all that distro testing. As for the mouse, I see you've already been searching around for answers, I hope that the selections you've found will be the answer. If they aren't, please feel free to make a post. We do try very hard to have VL working out of the box for as much hardware as possible, but sometimes some things just slip by somehow.
