I have 3 USB ports out of which one of the ports doesn't work anymore. 
Other 2 USB port works fine through which I use external devices like pendrive 
and hard disk sometimes when needed.

About the touchscreen, it works/responds fine. Is there something wrong
with my touchscreen?

I think the real culprit is, kernel trying to giving too much attention
to usb2 port and this is causing the laptop to not suspend properly.

Is there something we can do about this? @ddstreet
