Bluetooth and WiFi are different standards for wireless communication. Bluetooth version 3 and version 4 have higher data rates, but the actual data transfer in those implementations happens over Wi-Fi Bluetooth is only used to set up and negotiate the connection. So no, Bluetooth is not faster than Wi-Fi.
USB 2.0, on the other hand, allows for transfer speeds of up to 60 MB/second.
The highest speeds available on Bluetooth 2.0 are about 3 MB/second. The difference in data transfer speeds between USB and Bluetooth can be quite extreme.
