    I'm using XP Sp2 and my PC has USB 2.0 ports. I had no problem with my usb ports until yesterday. I plugged a USB extension port to one of my USB port. Windows found a new device (usb root hub) and I plugged my usb pen drive to one of the extension port. But windows did not show any devices plugged in. I thought that may be the extension port is not right and I unplugged the hub. Then I plugged in my pendrive to one of my usb port. Windows recognizes the pendrive but a msg pops up saying "this device may work well if plugged into a high speed port"(something like that). Then I plugged the pendrive in my laptop(runs on Vista) and I get the same msg. What's wrong with my usb ports? They used to work fine before. Today I plugged in my pen drive to my pc and I get a msg saying usb device not recognized!!!! All the ports pops up this msg and one of the port doesn't recognize any device not even my printer!!

    How can I fix this problem? What could be the problem?
    I have checked Device manager and there is a Enhanced Usb controller.

    p.s. Usb extension port is for usb 1.1
