    },
}

Protocol offered to [UsbFunction] instances to handle host-initiated requests.

Variants

Control

Callback for handling ep0 control requests.

setup is the control request to handle. write is the data to write to the endpoint. read is the data to read from the endpoint.

Fields

setup: UsbSetup

write: Vec<u8>

responder: UsbFunctionInterfaceControlResponder

SetConfigured

Inform the function driver when the USB device configured state changes.

Called with configured == true in response to a SET_CONFIGURATION control request that selects a configuration that contains this function. In this case, the function driver should use [fuchsia.hardware.usb.endpoint/Endpoint] to configure its endpoints.

Called with configured == false when configuration is disabled or USB is disconnected. The function driver should then use [fuchsia.hardware.usb.endpoint/Endpoint] to disable its endpoints.

Fields

configured: bool

speed: UsbSpeed

responder: UsbFunctionInterfaceSetConfiguredResponder

SetInterface

Called to set an alternate setting for an interface due to a SET_INTERFACE control request.

The function driver should use [fuchsia.hardware.usb.endpoint/Endpoint] to configure or disable the interface’s endpoints as appropriate.

Fields

interface: u8

alt_setting: u8

responder: UsbFunctionInterfaceSetInterfaceResponder

#[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: UsbFunctionInterfaceControlHandle

method_type: MethodType
