I just got a Roku Stick but my TV has no USB Port just an HDMI Port. So I can Plug my Roku Stick into the TV but I have to use the USB Cable that go from the Roku Stick to the AC Adapter. But the USB Cable that goes from the Roku Stick to the AC Adapter is to Short. So I will Buy a Longer USB A Cable. But the Part that goes into the Roku Stick is that a USB Mini B or what?
