I have been using a WIRED mouse with my new iMac (also have the trackpad). They mouse works great in OS X. When I boot into bootcamp Windows 7 Pro it works if I plug it in, but does not work if it is ALREADY PLUGGED IN. (ie have to plug it out of the USB port and back in for it to work) Is this a known thing or is there a fix? I have installed all the windows drivers for Mac. Thanks!
