Re: usb for P4VMM2
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.

If you already tried to clear the bios settings of your motherboard or change the bios settings but still the same. The best solution for you is to buy a pci (Peripheral Component Interconnect) card with usb port commonly with 4 usb ports. The pci card will install on your free pci slot on your motherboard and depends with your operating system if the card will plug and play or manually install using it's driver.
During the initial boot sequence (as soon as you turn your PC on), try pressing <DEL> button (or F2 or F10 - you will see info on the bottom of the screen stating something like "Press _____ (del, F2, F10) to go to Setup..."
This will take you to BIOS, main setup panel for your PC. There you can find and option for switching your main GFX card. Options will be something like: onboard, pci, agp. You should choose PCI.
Try doing this after you insert your new PCI gfx in your computer.
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.
shademon - I'm assuming that the drive letter change didn't help? If not, here's the deal. When you installed Vista over XP you may not have had all of the correct drivers installed. There is still an option. Try going to microsoft update and running cutom updates, down the lefthand side you should see a list of "hardware" updates download and install all of those, perhaps there is a driver update for vista. If that doesn't work you probably have a few ports that are direct soldered to your mobo, but you've probably also got a few in the front that run on a 4 - 8 pin cable to your board. You can also buy a card that should go into your vacant PCI slots (make sure it's vista capable) and you should be able to install the drivers/software direct via a CD with the new hardware check out these products newegg is pretty reasonable price http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&DEPA=0&Order=BESTMATCH&Description=PCI+USB hope this helps let me know if I can answer anything else.
reseat the video card in the slot. then use the cmos reset jumper on the motherboard (when the power is off). if this doesn't fix the issue, then the card may not be compatible with the agp or pci-e slot that is on your motherboard. If this doesn't work (I am assuming your motherboard also has a default (onboard) vga out port - then go into the bios and set the primary display device to be the agp or pci-e slot.
