help
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).
config BT_HCIUSB_SCO
bool "SCO (voice) support"
depends on BT_HCIUSB
help
This option enables the SCO support in the HCI USB driver. You need this
to transmit voice data with your Bluetooth USB device.
Say Y here to compile support for SCO over HCI USB.
