I have had Ubuntu 12.04 64 bit ever since its release and now just a few days ago i updated the kernel and a few other important security updates. Now my keyboard and mouse don't work after booting into Ubuntu. I have a triple boot and they work in windows Xp. even at the GRUB they work smoothly. Its only after booting up in Ubuntu 12.04 that they dont work. Its seems as if they are not detected at all since the lights on the keyboard and mouse intermittently go off.
Is this a known issue? I am hoping some updates are to blame. Please assist in fixing this.
