![]() ![]() The reset mechanisms work only for internal devices so externally-pluggable Bluetooth radios such as dongles are not supported. GUID_DEVICE_RESET_INTERFACE_STANDARD defines two levels of reset. While there are different approaches to recover from a failed state, Bluetooth uses a standardized ACPI-based recovery mechanism to attempt to restore the radio to a working state. The Bluetooth Reset and Recovery mechanisms described below are used in these cases. These are failures outside of the enumeration pathway and could be general critical transport-specific failures or device-specific failures such as a catastrophic firmware error. Non-enumeration failures: The device is not in a failed state but is otherwise non-operational as seen by the driver stack. An example of such an operation could be a firmware download to the device. Failures could occur if a driver encounters an error during one or more start operations and as a result reports a PnP failure. when a filter or function driver is installed on the Bluetooth radio device node (devnode). This typically occurs when building up the driver stack for the radio, e.g. ![]() ![]() There are three broad categories of issues where Bluetooth Reset and Recovery is initiated:īus enumeration failures: The radio fails enumeration or re-enumeration by the underlying bus (for Bluetooth, this is typically USB or UART) as indicated by a visible failed state (yellow bang) in Device Manager, which may be symptomatic of underlying hardware errors.ĭriver enumeration failures: The Bluetooth radio is in a failed state after successful enumeration by the underlying bus.
