The old Home Hub 5 had a usb socket. If you connected a portable hard drive to this usb port you could then read the hard drive through the file explorer in the network section. (W7 and W10). This does not work with the new Smart Hub. If you look in the hub user interface the hard disk is there but in file explorer it cannot be found. No settings have changed on the laptop. I can't find any settings in the hub user interface that would influence this. Any help would be appreciated.
