FireWire is always a sure thing for Bus Power... but the 80GB SATA 2.5" should power via USB no problem on the desktop, the MacBook Pro (one of the ports may be higher power than the other due to the iSight sharing.
Make sure the switch on the enclosure is set to the Bus Power side vs. the AC Power side.. I can't say 100% with the USB2 case off the top of my head, but several of the enclosures will have the drive activity light power on when there is signal but no actual power.
