thx for reply , i wasn't around...
well i sure have usb port and ti is wired directly , i'm not using hub,
not sure which version it is 1.1 one or earlier , my pc is about 4 years old . i just wanted to know if there's a big performance difference
between usb 1 and usb 2 , is it worth upgrading to usb 2
thx
