pub struct Device<T: UsbContext> { /* private fields */ }

Expand description

A reference to a USB device.

Implementations

source

impl<T: UsbContext> Device<T>

source

pub fn as_raw(&self) -> *mut libusb_device

Get the raw libusb_device pointer, for advanced use in unsafe code

source

pub fn context(&self) -> &T

Get the context associated with this device

source

pub unsafe fn from_libusb(
context: T,
device: NonNull<libusb_device>
) -> Device<T>

Safety

Converts an existing libusb_device pointer into a Device<T>. device must be a pointer to a valid libusb_device. Rusb increments refcount.

source

pub fn device_descriptor(&self) -> Result<DeviceDescriptor>

Reads the device descriptor.

source

pub fn config_descriptor(&self, config_index: u8) -> Result<ConfigDescriptor>

Reads a configuration descriptor.

source

pub fn active_config_descriptor(&self) -> Result<ConfigDescriptor>

Reads the configuration descriptor for the current configuration.

source

pub fn bus_number(&self) -> u8

Returns the number of the bus that the device is connected to.

source

pub fn address(&self) -> u8

Returns the device’s address on the bus that it’s connected to.

source

pub fn speed(&self) -> Speed

Returns the device’s connection speed.

source

pub fn open(&self) -> Result<DeviceHandle<T>>

Opens the device.

source

pub fn port_number(&self) -> u8

Returns the device’s port number

source

pub fn get_parent(&self) -> Option<Self>

Returns the device’s parent

source

pub fn port_numbers(&self) -> Result<Vec<u8>, Error>

Get the list of all port numbers from root for the specified device
