Any experiences with power hungry USB devices?

I'm working on documenting various aspects of our USB port.

We believe that the FreeRunner USB port should be capable of delivering 
the standard USB high current of 500mA. We also believe that we respond 
properly to USB negotiation of this current, up from the minimum of 100mA.

I suddenly remembered that someone posted about using a USB keyboard 
that didn't work due to high current. However, the FreeRunner should be 
able to provide exactly as much current as a desktop PC, which I assume 
works with this keyboard.

If any of you have experienced difficulty with the FreeRunner powering 
USB devices, please speak up.
