Has anyone found a USB Hub that will provide enough power to support all of the devices that an onboard Apple USB port will? One port must supply the mouse and keyboard, that leaves one for a Hub, but if you have a device that balks at Hub connection, you have to disconnect the Hub (and anything connected to it) in order to run it. I've been using different Belkin Hubs with less than satisfactory results. The device I am having trouble with is an EyeOne Pro which is referred to in its spec sheet as a "high power" USB item. DaleH
