Caveats

• Raspberry PI support a USB bus tree of max depth 5. Consider that bus extenders usually contain 3-4 levels each.
• The current provided by the card to the USB bus is 500 mA max. Check the requirements of what you attach to the USB bus. In case, take power from elsewhere (e.g., for Arduino), or use a powered bus extender.
