For those wondering, that is a wireless nic, and it is also locally connected to the switch. The box is a raspberry case with the pi logo on it. On top, using the pull tape (best seen in the first picture) I have attached a powered USB hub.
In this case, the pi can be powered from the hub by plugging the hub into the wall, or from any USB port (even that of the Xbox 360, tested and working). The hub is a great addition because it is able to power devices, whereas the pi USB power is very lacking for obvious reasons.
