    my windows cannot recognize any of usb device

    Hi, Unplug the USB device, and then plug the device back into the computer or hub. If your computer still does not recognize the device then, Click Start, click Run, type Devmgmt.msc, and then click OK. The Device Manager window opens. Expand Universal Serial Bus controllers. Right-click a USB Root Hub in the list, and then click Properties. The USB Root Hub Properties dialog box is displayed. Click the Power Management tab. Click to clear the Allow the computer to turn off this device to save power check box, and then click OK. Repeat steps 3 through 6 for each USB Root Hub in the list. On the Action menu, click Scan for hardware changes. Windows XP recognizes the new device. Close the Device Manager window. http://www.techyv.com/questions/windows-cannot-recognize-usb-device
