The difficult question is how to DISABLE USB-ports. If you know how you did that, just undo. If you don't know, do it the sure way: a clean reinstall of the OS. By default, all ports are enabled. Be sure to install the motherboard drivers also or they might not work.
I am using an XP machine in my office and has the administrator rights.I wanted to enable the USB ports in the machine.I have gone through a lot of sites which says how to enable the USB ports by making changes in the registry and all,but all for vain.
Please can someone help me in this regard.Also is there some software which can enable the USB ports automatically.
