Powered USB hub

Apologies for what must be a very simple question. I'd be grateful if someone could tell me the advantages of using a powered, rather than a unpowered, USB2 hub. Is it just a matter of supplying necessary power to a particular device? If so, what devices would need one? Would using one if it isn't actually required be OK?

Many thanks.

Deininately preferable.
An unpwered hob relys on the PC power supply, which with some devices -a scanner say can be considerable and affect the computers performace. It does not matter too much for card readers or mice etc.,
More over even here if devices not being used are left plugged in they will all be havine there 'pull'
and can actually stop the msachine or at least not read.
The rule here is if you are not using it pull it out and if you can power it separately.
