@rdc85, done that already but nothing happens.. all related to usb or mouse were already enabled.
it seems that there is something that the motherboard suddenly doesn't like about the mouse.. or its settings...maybe drivers.. Not really sure if there was recent update with the drivers. but my logitech controller can use any usb slot w/o encountering similar problem. I simply cannot use the mouse to any usb slot w/o re-attaching it after powering on. This is kinda weird.. ~_~
