I agree with BJL. It's practically ridiculous to not be USB 2.0 capable. Practically every PC and peripheral device on the market today is 2.0 equipped. Some use both that AND 1394 and others use 2.0 alone.
The USB port is only for direct printing, it will not work for image transfer or tethered shooting. The firewire port must be used for those purposes. So 1.1/2.0 is kinda moot.
