DerbyDave - yes, usb type b, I googled it and that is def. It. I have not plugged anything into it because I can’t find an adapter that would go usb b to anything useful (thumb drive, etc). Where it comes out does make me think maybe it does come from the back of the much, but I don’t know, maybe drop into the local computer store and ask what it a usb b to sod adapter????
