when you plug in the usb to the system it will ask for driver, point the installation manager to where you put the driver after you installed the system program tool. if you have tried th install driver and it failed, you will have to go in to control panel - system - device manager, you should see a yellow circle with ! in it,open this( named kxtda/panasonic) and reinstall driver

“I have not failed. I've just found 10,000 ways that won't work.”
