Variants

GetConfiguration

Retrieves the current device descriptor and active configuration descriptors.

Returns the active USB device descriptor and all associated configuration descriptors registered with the peripheral device manager.

• error:
  • ZX_ERR_BAD_STATE: The peripheral device has not been configured.

Fields

responder: DeviceGetConfigurationResponder

SetConfiguration

Sets the device’s descriptors, adds the functions and creates the child devices for the configuration’s interfaces. At least one function descriptor must be provided.

Fields

device_desc: DeviceDescriptor

config_descriptors: Vec<Vec<FunctionDescriptor>>

responder: DeviceSetConfigurationResponder

ClearFunctions

Tells the device to remove the child devices for the configuration’s interfaces and reset the list of functions to empty. The caller should wait for the FunctionsCleared event.

Fields

responder: DeviceClearFunctionsResponder

SetStateChangeListener

Adds a state change listener that is invoked when a state change completes.

Fields

listener: ClientEnd<EventsMarker>

control_handle: DeviceControlHandle

#[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: DeviceControlHandle

method_type: MethodType
