Enum ConfigurationRequest 

pub enum ConfigurationRequest {
    GetConfiguration {
        responder: ConfigurationGetConfigurationResponder,
    },
    SetConfiguration {
        device_desc: DeviceDescriptor,
        config_descriptors: Vec<Vec<FunctionDescriptor>>,
        responder: ConfigurationSetConfigurationResponder,
    },
    #[non_exhaustive]
    _UnknownMethod {
        ordinal: u64,
        control_handle: ConfigurationControlHandle,
        method_type: MethodType,
    },
}

Protocol for querying and dynamically reconfiguring USB peripheral functions.

Enables policy managers and system command-line tools to inspect active USB peripheral configurations and reconfigure the peripheral device function stack at runtime.

Variants

GetConfiguration

Retrieves the current USB device descriptor and active configuration descriptors.

Errors

• ZX_ERR_NOT_SUPPORTED: Peripheral function querying is not supported on the target hardware.

Fields

responder: ConfigurationGetConfigurationResponder

SetConfiguration

Sets and activates a new USB peripheral function configuration.

Teardown of the previous peripheral function stack occurs before initializing and binding the newly specified functions. The call completes once the peripheral controller and underlying function drivers are registered and ready.

Errors

• ZX_ERR_INVALID_ARGS: Configuration parameters are invalid.
• ZX_ERR_ALREADY_BOUND: An existing peripheral configuration is locked or undergoing transition.
• ZX_ERR_NOT_SUPPORTED: The requested combination of functions cannot be supported simultaneously.

Fields

device_desc: DeviceDescriptor

config_descriptors: Vec<Vec<FunctionDescriptor>>

responder: ConfigurationSetConfigurationResponder

#[non_exhaustive]

_UnknownMethod

An interaction was received which does not match any known method.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

ordinal: u64

Ordinal of the method that was called.

control_handle: ConfigurationControlHandle

method_type: MethodType
