I just got a Microsoft Basic Optical Mouse for only $6.99 online, which is a great price; however, when I plugged it into my Inspiron 1100, it is recognized but not installed.  I keep getting missing hidusb.sys and mouhid.sys errors.  Microsoft doesn't have any driver recommendations, but I find it curious that it wouldn't work - since it is a USB mouse.  The mouse doesn't support IntelliPoint software, so what should I do?  Has anyone else had this problem with these mice?  Thanks.
