I have an old ibm usb wired mouse that I am using it on a Windows 7 x64 computer. (The mouse was originally used on a Windows xp machine.) The mouse is working fine, until I turn off the computer. Upon reboot, sporadically, the mouse will be frozen when the machine boots up. Most times, if disconnect and reconnect from the usb port, the mouse will work ok. However, I am running out of usb ports, because after a number of such on-and-off cycles,the mouse will not reconnect in that port. Is there any way of fixing this, short of buying a new mouse? I would be grateful for any help. Thank you.
