Attached please see these updates from the manufacturer for my Asus P5LD2 Motherboard . I have both these problems of Post hanging at USB detection (if a USB or any other drive is already connected to the computer when I start it) and USB controller disabling if BIOS default is used (When this happens I usually have to go to the BIOS and reset it). I am hesitating with these because of the risk involved in trashing my Motherboard if something goes wrong. Your opinions are most welcome. Should I do these updates or not?
