Expand description

A trait which represents a USB context.

Required Methods§

Source

fn device_by_id_with_timeout( &self, usb_vid: u16, usb_pid: u16, usb_serial: Option<&str>, timeout: Duration, ) -> Result<Box<dyn UsbDevice>>

Find a device by VID:PID, and optionally disambiguate by serial number.

Source

fn device_by_interface_with_timeout( &self, class: u8, subclass: u8, protocol: u8, usb_serial: Option<&str>, timeout: Duration, ) -> Result<Box<dyn UsbDevice>>

Provided Methods§

Source

fn device_by_id( &self, usb_vid: u16, usb_pid: u16, usb_serial: Option<&str>, ) -> Result<Box<dyn UsbDevice>>

Find a device by VID:PID, and optionally disambiguate by serial number.

If no device matches, this function returns immediately and does not wait.

Source

fn device_by_interface( &self, class: u8, subclass: u8, protocol: u8, usb_serial: Option<&str>, ) -> Result<Box<dyn UsbDevice>>

Find a device with a specific interface, and optionally disambiguate by serial number.

If no device matches, this function returns immediately and does not wait.
