My USB port cannot recognized

I am using windows XP and I have cleaned some of my item from my computer to get space. Now I cannot insert memory card, phone for photo via USB.
For every time I was trying to insert it, it had shown the message "Found new hardware – cannot install this hardware there was a problem installing this hardware. USB Mass Storage An error occurred during installation of device. The data is invalid. Click finish to close wizard".
What can I do now to solve it?
