Thats what im trying to connect (a 2.5"HD to my PowerBook G4) but apparently one usb port isnt enough to power my 2.5"HD. The Y cable the 2.5" enclosure comes with cannot connect to the one extra usb port cause its on the other side and it cant reach. What can i do, any ideas? A USB hub? Has anyone tried this? What USB hub model is it?
