I'm trying to update via the usb extension cable but my stick isn't being detected. Then I wondered if the bluetooth dongle was working, I can't see any evidence of this, nothing in settings and my mobile isn't finding anything when searching for bluetooth devices. Is there anywhere in the settings where I should be able to see the dongle? I've also read to try a different usb socket on the pc but there aren't any free ones that I can see. I'm more than likely going to have to get a different stick but just wanted to eliminate the extension cable first.
