DRIVERS

Some Bluetooth controllers require a driver to function properly. This may include, for instance, loading a Firmware image or patch, loading a configuration.

By default, drivers will be automatically probed to determine if they should be used with particular HCI controller. When the transport for an HCI controller is instantiated from a transport name, a driver may also be forced by specifying driver=<driver-name> in the optional metadata portion of the transport name. For example, usb:[driver=rtk]0 indicates that the rtk driver should be used with the first USB device, even if a normal probe would not have selected it based on the USB vendor ID and product ID.

Drivers included in the module are:

• Realtek: Loading of Firmware and Config for Realtek USB dongles.
• Intel: Loading of Firmware and Config for Intel USB controllers.
