ive just tried to work out why the front USB ports dont work and it seems there are no USB headers to connect to the motherboard from the front.
there are however two USB to USB header cables like below which were located near the top so could be something to do with the front?
the front only has the 1394 cable actually connected and the usual power SW, reset SW and lights e.t.c
for connecting to the motherboard.
now, is your case the same or have i just got gotten all muddled up & confused and if your front USB does work where are the cables connected to?
*im sorry if i sound really confusing, it is quite hard to explain!*
