USB is powered by a current limited 5.0 volts supply. Normally even if there is a short circuit, the port is well protected but if a higher voltage is applied from outside (defetive USB device) the port can be damaged. There is a very small fuse or fusible resistor in the PCB. Unless it is burned, it is difficult to find. You can try to look near the area of the USB socket. If you were lucky enough to find it, you can replace it.
Another possible solution - connect a USB hub with external power supply to one of the USB ports in your PC. If the datalines of our internal USB is still OK, then you can use this HUB. The power will come from the externel supply. Connect the USB devices on the hub and not on the PC.

Quite easy buy one from fry's online a 4 port pci slot type and remove the two screws on one side pull the safety plate off the PCI slot off the case and install the PCI card into the mother board and install screw and run the DVD to make the usb ports work and pt lid back on and your set to go.
The message comes up when a USB 2 device is connected to a slower USB 1 or 1.1 port. It is only to advise you that the devise will operate faster on a USB 2 port. If your computer has only USB 1 or 1.1 ports, you will always see the message. You can buy and install a card with USB 2 ports and install it. It will come with the USB 2 drivers. Install the card and the drivers and then connect your USB 2 device to the new hardware and you should not see the message anymore.
Good luck, And let me know ho it works out for you.
