It could be that the device may have not been recognised first time round, have a look in Device Manager (Control Panel then System then Hardware) to see if there are any unknown devices - they usually have a yellow question mark.
If you have any you could try uninstalling them and restarting then plugging it back in - might work ???
I have looked and I don't have anything in my Device Manager it is completly empty.
Thank you to everyone who has supplied help and advice it is really appreciated
