Rod,

Are you trying to plug into the USB ports on the Keyboard, or the back of
the Mac?

My Wacom tablet won't work from the keyboard USB ports, but happily ran from
the back of my Blue & White G3. It now runs from a powered USB four port hub
which sits beside the monitor making it easier to plug and unplug devices. I
was advised that a powered hub was best for these higher power devices. Not
sure if this is true in all cases.

Regards,
John

Yes this is the case John.

A self powered Hub will provide 500mA per port, where as Bus Powered hubs can only supply 100mA per port (due to the upstream port supplying the hub with a maximum of 500mA)

Kat.
