This one was a headache! I got all drivers loaded properly for Panasonic CF-53 in Windows 7, except one unknown device, which was actually a USB 3.0 Hub driver. It would not load the traditional way, so what I ended up doing was taking the drivers, and putting them on the image itself under C:\windows\inf folder
If you would like the drivers, you can get them here :
