Example #2

File: usb.go Project: hanwen/usb

// Get the number of the bus that a device is connected to.
func (d *Device) GetBusNumber() uint8 {
	return uint8(C.libusb_get_bus_number(d.me()))

Example #3

File: eeprom.go Project: sstallion/go

// ID returns a string suitable for uniquely identifying the device.

	bus = int(C.libusb_get_bus_number(dev.device))
	addr = int(C.libusb_get_device_address(dev.device))
