"""
Report connected FTDI devices. This may be useful in obtaining
serial numbers to use as the device_id parameter of the Device()
constructor to communicate with a specific device when more than
one is present.
example usage:
$ python pylibftdi/examples/list_devices.py
FTDI:UB232R:FTAS1UN5
FTDI:UM232R USB <-> Serial:FTE4FFVQ
To open a device specifically to communicate with the second of
these devices, the following would be used:
>>> from pylibftdi import Device
>>> dev = Device(device_id="FTE4FFVQ")
