The rpi has only two USB ports which are often used by a keyboard and
mouse and then you need a few more ports ie memory stick, external 2
1/2" harddisk etc
A powered USB hub is often used to provide more USB ports and also if
the hub has a 2 amp or more external power supply provide the 5VDC to
power the rpi itself.
A model B rpi only uses around 800mA or around 4 watts.
Bunnings have a 2000 mA 5VDC seven usb port powered hub for around $30
which works well with a rpi.
Jaycar and many other places sell powered usb hubs, just make sure that
it has a minimum 2 amp supply.
Alternatively use a spare USB phone charger or a cigarette lighter usb
