Hello: I have been encountering this annoying problem and I would appreciate anyone's help in working around it. I have been building and updating several systems, including updating system bios, chipsets, etc. Whenever I update an enhanced USB controller driver (as part of an Intel-based chipset), if the system is using a USB-based keyboard or USB-based mouse, those specific devices freeze up/stop running. Unless the system is using a PS-2-based keyboard or a PS-2-based mouse, I have to do a "hard" shutdown, to restart the system and get the newer enhanced USB drivers installed. Of course, I hate doing this and wince every time I do the "hard" shutdown. So far, I have been lucky and the systems have always come back up, with the new enhanced USB drivers installed. However, I would love to know how I could update the enhanced USB drivers, without having to perform a "hard" shutdown of the system. Moreover, most of these systems do not have a PS-2 port; therefore, using an older, PS-2-based mouse or a PS-2-based keyboard is not an option, unfortunately. What is the proper procedure for updating the enhanced USB drivers, via the Intel â€œHave Diskâ€ method, whereby, I can get around the USB-based keyboard and USB-based mouse freeze up issue? Any information would be wonderful. Thank you.
