I'm not too sure why, but every single time I boot my computer, I have to unplug and replug my semi-new Microsoft Habu, when I use Windows 7. Why does it do this? I've been through my BIOS, msconfig, and what-not.. It just seems to happen all the time. I've even looked in forums, with people resorting to changing their mouse because of the same issue.. It's stupid. Hopefully someone else can help... hopefully someone with experience with this mouse.
