I've read the reply here that the USB power cable is needed for USA1 use.
I had already plugged my MS PS300U2 into the USB1 port on my Mac G4 and it mounted OK, but I didn't go any further.
Since it mounted will it run OK on USB1 without the power cable? I don't want to damage it, but I'm short the second port and would have to get a powered hub.
TIA
