![]() ![]() ![]() 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.
