hmm that looks like your laptops touchpad and keyboard...no usb possible....
Furthermore, when I plug in the little receiver for the mouse, it automatically downloads and installs a driver for it.
This is the windows update doing the driver install... you can stop this by going to system properties... and choosing the option as shown below (right click Computer icon and select properties)
One you done this.... remove both the mouse and keyboard.... and then install the drivers from targus and keyboard..... once finished... plug the mouse and keyboard to another usb port rather than the one you have it normally plugged...
this should get the targus driver installed..
Then try the above command and let me know
