Types

type USBDevice

type USBDevice struct {
	Serial     string
	DevicePath string
	HubPath    string
	DeviceType string
}

USBDevice represents a plugged in USB Device

func FindServoFromDUT

func FindServoFromDUT(dutSerial string, devices []USBDevice) (USBDevice, error)

FindServoFromDUT finds the Servo associated a given serial number from a DUTs cr50/ti50 by comparing the USB hub path. Both a Servo and a device plugged into a Servo will be enumerated under the Servos built-in hub in the USB device tree.

func GetAllServoUSBDevices

func GetAllServoUSBDevices() ([]USBDevice, error)

GetAllServoUSBDevices returns all the USBDevices instance of plugged devices

func NewUSBDevice

func NewUSBDevice(path string) (*USBDevice, error)

NewUSBDevice is a constructor for USBDevice
