I have an Asus A78NX - Deluxe Rev 2.0 using Bios 1007. My keyboard suddenly decided to stop working through the USB port, it has been working correctly for about a year. I am now using this keyboard through the PS/2 port using a USB to PS/2 adapter. I tried other USB ports, on the motherboard and on a add on card and nothing changed. Does anyone have a clue on this? or experienced a similar issue? Thanks for the help.
