my pc has 6 usb ports two in front 4 in rear im assuming they are on sum sort of hub but ive tried it in all 6 and it doesn work plus my old net md worked fine in the two front ones using openmg. specs rare celeren running at 2.4, 512mb ram, 120gb hd, dvd-cd drive xp operating system erm other than that pretty ordinary machine. when i go into the device manager it has a yellow dot with an exclamation mark over the hi-md usb branch ive tried reinstalling the driver but the pc claims it's invalid. im starting to think it's a pc fault but i figured i'd ask u gurus first but im gonna go home and install 3.2
