Why don't my USB ports work?
I've noticed recently that both of the USB ports on the right side of my G71 are not working correctly. Whenever I plug a device into the top one, I get a "USB device not recognized" message, and plugging something into the other gets nothing at all. The third USB port (on the left side) works perfectly fine.

Try reloading the USB drivers. Cheapest easiest fixes first then dive in to innards.
