I'm looking to buy an external hard drive but I'm not sure how to tell if I have USB 1.1 or USB 2 ports. I've looked on Device Manager but I'm none the wiser. I am using Windows XP.

USB 2 will display as 'Enhanced'.

tadpole1, what computer, or motherboard do you have?

It all depends on the construction of the motherboard, in the event there is nothing you can do about it.
In the event USB 1&2 are interchangeble and it does not matter. You are likely to obtain a new device as USB2 , 1 having now been superceded for some time.
You may gae a nag saying this USB2 device would operate better on a USB 2 conputer. but in everyday useage terms you will see no diference.

It is possible to a. turn off the Nag -I am not sure how , others will come to the rescue on this I am sure.
or purchase a USB2 PCI card
But to my mind you would be chasing around for nothing very much, although a card is a better bet than a hub for extra ports.
Go ahead and get the drive of your choice - it will work just fine.

If you are going to use the drive for backup, you really need USB 2. Otherwise the data transfer will take hours.

USB 1 12Mbits/second

USB 2 480Mbits/second

I'm not sure what motherboard I have got (I'm a bit of a novice) My computer is Pentium 4 CPU 2.60Ghz 512 MB of RAM. If I'm not sure if I have got 1.1 or 2 am I better off buying an external disk drive using Firewire?

If you have a spare PCI Slot, you can fit a USB 2 card in it. This will normally have at least two USB 2 sockets on it, and are quite cheap.

Happy New Year

As above, the key word is 'Enhanced'. This means USB 2.

On one of my USB hubs it says 'SiS PCI to USB Enhanced Host Controller'. Is this USB 2 then? The others all say 'SiS 7001 PCI to USB Open Host Controller'. Can you have USB 1.1 and USB 2 on the same PC?
