Welcome to the Apple Discussions.
Powerbooks don't put out much power on the USB port, and it's not unusual for external devices that rely on power from the USB port to not function properly. Several options:
If the adapter also has a firewire connection, use that
Get an external power adapter
Use a powered USB hub
Get one of the USB cables that has two USB plugs for the Powerbook side
