Today USB is the most successful interface in the history of personal computing. We all use it all day every day. It is the one thing that many would consider impossible to imagine your day without.

The best solution, though, is to simply opt for a powered USB hub. This will enable you to use your USB hub for not only a device or two but a whole slew of devices without ever worrying about under-powering them.
