Implementations§

source§

impl DeviceProxy

source

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.hardware.usb.device/Device.

source

pub fn take_event_stream(&self) -> DeviceEventStream

Get a Stream of events from the remote end of the protocol.

§Panics

Panics if the event stream was already taken.

source

pub fn get_device_speed(&self) -> QueryResponseFut<u32>

Returns the speed of the USB device as a usb_speed_t value.

source

pub fn get_device_descriptor(&self) -> QueryResponseFut<[u8; 18]>

Returns the device’s USB device descriptor.

source

pub fn get_configuration_descriptor_size( &self, config: u8 ) -> QueryResponseFut<(i32, u16)>

Returns the total size of the USB configuration descriptor for the given configuration.

source

pub fn get_configuration_descriptor( &self, config: u8 ) -> QueryResponseFut<(i32, Vec<u8>)>

Returns the device’s USB configuration descriptor for the given configuration.

source

pub fn get_string_descriptor( &self, desc_id: u8, lang_id: u16 ) -> QueryResponseFut<(i32, String, u16)>

Fetches a string descriptor from the USB device.

desc_id : The ID of the string descriptor to fetch, or 0 to fetch the language table instead.

lang_id : The language ID of the string descriptor to fetch. If no matching language ID is present in the device’s language ID table, the first entry of the language ID table will be substituted. actual_lang_id : The actual language ID of the string fetched, or 0 for the language ID table.

The worst case size for the payload of a language ID table should be 252 bytes, meaning that a 256 byte buffer should always be enough to hold any language ID table.

The worst case size for a UTF-8 encoded string descriptor payload should be 378 bytes (126 UTF-16 code units with a worst case expansion factor of 3)

source

pub fn set_interface( &self, interface_number: u8, alt_setting: u8 ) -> QueryResponseFut<i32>

Selects an alternate setting for an interface on a USB device.

source

pub fn get_device_id(&self) -> QueryResponseFut<u32>

Returns an implementation specific device ID for a USB device. For informational purposes only.

source

pub fn get_hub_device_id(&self) -> QueryResponseFut<u32>

Returns the implementation specific device ID for the hub that a USB device is connected to. For informational purposes only.

source

pub fn get_configuration(&self) -> QueryResponseFut<u8>

Returns the device’s current configuration.

source

pub fn set_configuration(&self, configuration: u8) -> QueryResponseFut<i32>

Sets the device’s current configuration.
