To complete what you have said above for others (as this is a common problem)
Take your laptop battery out and the mains lead. Leave it for a minute or so for power to drain out of system.
This resets the usb chip which will then rediscover your ports etc when you plug power back in and switch on.
Has it worked for you?
If so don't forget to report to the Mods as problem solved for your "green tick"
