Piece of cake.

Make sure you have an SD card mounted
Turn on USB debugging
Turn on Unknown sources
Install it
Run it

BOOM. Root.

i too faced the same problem...try following...

1) do factory reset (settings/privacy/factory reset)
if it doesnt works....
2) connect your phone to computer via usb cable..,but dont turn on mass storage....uninstall previously installed drivers, pc sync softwares on ur computer....and freshly download the usb drivers only from the lg official site.........

this is what i remember......just try...........
