I have a Toshiba satellite L505D, and the USB's and the volume all of a sudden quite on me. I'm normally good with computers but I've never had this problem, and yes, I've tried basically everything a normal person would do, from re-installing the drivers, to resetting my computer, restoring it, everything. And nada. Nothing works. If you know what could be the problem, please let me know. ;-;
do they showup in device manager at all? have you tried going into the bios to see if they are disabled?
