I have a toshiba sattilite l305 running 12.10 64bit

I was using the lappy and the touchpad quit working, I decided to hook up a usb mouse the light on the mouse came on but the mouse would not move on the screen.

so I booted using 12.10 cd wanted to see if the problem would go away. when I booted using the ubuntu cd the touchpad still didn't work and the mouse didn't work.

is this a Hardware proublem? and if it is can it be fixed/replaced or am I just screwed?
