My lexmark printer on occation just stop communicating with the computer. Windows xp will see it and try to install the driver again if I uninstall it but it wont work unless I actually change the USB port it's plugged in to. I've done this three times and now i have three Lexmart Virtual ports. One is usb001 then usb002 or something like that. I'm running out of free usb ports, and plugging the printer cable back into the previous ports wont work. How do I fix this problem? I have windows xp with service pack 2. I really need some help here.
