In Windows 8 and Windows 8.1, radios connected over alternate transports can be added via a third-party bus driver. The Bluetooth stack that is included with Windows 7 and Windows Vista does not support Bluetooth radio connections over PCI, I2C, serial, Secure Digital I/O (SDIO), CompactFlash, or PC Card interfaces. With Windows, a Bluetooth radio can be packaged as an external dongle or embedded inside a computer but it must be connected to one of the computer’s USB ports.
