Ever had this problem?
You plug in an USB memory stick and nothing happens. Windows does not ask you to install software or doesn't tell you that a new device is connected. Strange...
You might want to check the device manager, because in my case Windows try to give a drive name to the usb device that was already mapped. So it will not work properly.
Just assign a free drive letter to the USB memory stick and immediately a window will pop up showing it's contents.
