They (mouser) already charged my credit card...they better have it soon!

BTW, sorry about this question but I still did not understand the function of the BT:
Left Port: USB Hub with your Mouse and Keyboard/Gameboard
Middle Port: Console Controller Xbox One (via micro-USB cable), or Xbox 360, or Dualshock 3 (charged)
Right Port: Your Bluetooth adapter (what is its function?)

GOT THE ANSWER IN OTHER POST! 
Just got myself the adapter and hub Obsiv said to get. The one place doesn't have the adapters in stock but the other place digi key or whatever does. Got 2nd day shipping. Let it begin!!!!
Yeah unfortunately I couldn't order from Digikey, even when using a VPN it recognized I'm in Japan. I had to use Mouser to ship to an FPO address. Here's hoping that Mouser gets stock in earlier than they say. I'm keeping my fingers crossed!
