Plugging and unplugging USB cables I did something that has stopped the operation of all four USB ports. When I check the system hardware everything is operating as it should. Is this a mother borad problem? Could I have cooked something?

It will be useful if you post what you have done to try to correct this

I did what you had recommended to someone else: Click start then right click my computer, click properties then hardware, click device manager, scroll down to universal serial bus controller, click +

left click then right click an entry, click delete, confirm, repeat this until all the entries are gone.

Reboot the PC then plug a USB lead in

In my case, it made no difference.

Could we also have your system specs as well please?
In particular, the make & model of the motherboard, or if you have a big name computer (such as Dell or HP etc), then the make & model of the computer.

Thanks to all who offered help. I resolved the problem today with a USB cardbus adapter.
