A question about USB ports

My PC has two USB ports and is running Windows 2000 Professional.

One USB is used for a Palm cradle.  The other USB is used for a 4-port USB
hub.  And my USB mouse is plugged into this 4-port USB hub.

For some reason, *sometimes* after a Palm cradle hotsync, the 4-port USB hub
would "lose power".  My USB mouse would no longer work.  It would often be
resolved when I unplug and re-plug the 4-port USB hub.

Very frustrating.

Does anyone know why this happens?

Use a powered hub instead and this will not be an issue. You are simply
asking a port for too much power.
