Projector P1273 USB mini port -- is it a signal source? Brand new projector, just learning to use it. The manual, page 7, for button 22 on the diagram, which is the 0 key on the remote's keypad, says "Press USB B to change source to mini USB (USB B)." But it doesn't seem to work.  When pressed, I see in the projected image a small red circle with a diagonal line through it on top of an image of the remote control. I assume this icon indicates to me that the button is not an option. But why have two separate buttons for USB A source and USB B source (key 7 and key 0, respectively)? I strongly suspect the manual was written wrong. These two source buttons are for the two full USB ports on some other model in the series. Tech writer got confused. But I am seeking confirmation. I contacted Tech support via chat and they said there was a hardware issue, want me to mail it to a service facility. But I am doubtful. I think they just read the manual, too, during the chat. Can any other users please confirm how this button works for their projector? All I can do with the USB mini connection is page up and page down via the remote when in a Powerpoint presentation using those other buttons also found on the remote. Thanks.

    By the way, I am watching that powerpoint presentation via an HDMI connection. Nothing wrong there. The USB mini port is sending the page up and down instructions back to the laptop. The HDMI is not doing it.
