- Bluetooth HCI USB driver.
- This driver is required if you want to use Bluetooth devices with
- USB interface.
-
- Say Y here to compile support for Bluetooth USB devices into the
- kernel or say M to compile it as module (hci_usb).

- This option enables the SCO support in the HCI USB driver. You need this
- to transmit voice data with your Bluetooth USB device.
