Struct opentitanlib::util::usb::UsbBackend

pub struct UsbBackend { /* private fields */ }

The UsbBackend provides low-level USB access to debugging devices.

Implementations

impl UsbBackend

pub fn scan( usb_vid: u16, usb_pid: u16, usb_serial: Option<&str> ) -> Result<Vec<(Device<GlobalContext>, String)>>

Scan the USB bus for a device matching VID/PID, and optionally also matching a serial number.

pub fn new(usb_vid: u16, usb_pid: u16, usb_serial: Option<&str>) -> Result<Self>

Create a new UsbBackend.

pub fn get_vendor_id(&self) -> u16

pub fn get_product_id(&self) -> u16

pub fn get_serial_number(&self) -> &str

Gets the usb serial number of the device.
