I plugged in a usb device (memmory card reader) and I recived a messege. "USB Power Surge". Now my ipod and all usb devices (wireless mouse) are recognize as unkown devices and dont function. When i try to update the usb driver it says it could find no update better than the one i'm using. Is there a way to fix my usb to recognize my devices? I have usb 2 by the way.
 
I've seen that message before... after one of my cats decided a USB cable would make a nice snack. The cable connected my MIDI keyboard to a powered USB hub.

Rebooting the computer didn't fix it. I had to disconnect the USB hub from the computer and unplug the hub from the power outlet, then reconnect everything to get my computer to see the USB devices again.

If your card reader is connected to a powered USB hub, try what I did. If it's connected directly to your computer, try turning off your computer and turning it back on (not a soft-reset).

Good luck.
 
I take it that means you have the card reader connected directly to a USB port on your motherboard? Try turning your computer completely off and then back on to see if that fixes it first.
 
I doubt it... it sounds like the USB controller on your motherboard was toasted by the power surge. You should be able to find a PCI USB 2.0 controller card for less than $20 though.
 
Every once and a while one of the 16 USB devices I have malfunctions. To solve this I turn everything off, unplug ALL the cables, boot, then plug everything back in one at a time. I have read somewhere USB cables can build up interference in the cable. Unplugging it is a remedy. I dont know if this is true, but it seems to work for me.
