Leon,
I use a Targus 4 port usb Hub as per the link.
http://www.targus.com/au/product_det...sp?sku=ACH63US
It connects as normal to your lappy and will give you 4 operational ports.
If you need more power to the hub, it comes with a "Y" cable that has 2 usb connectors at the end.
One is for the tfr of data to and from (black), the other being solely for power (red).
No AC adaptor required - that has got to be a good thing
All is fine as long as you have 2 usb ports on your lappy if you need the power.
Retails for around $40.00
There are probably more out there by other suppliers also.
