USB to Serial devices #82

I am using several USB to serial devices. I want to recognize them before connecting (via pyvisa-py). To do that I use the following code:

def find_device_VISA(vid=None, pid=None, vendor=None, serial=None,
                    fmt='ASRL{}::INSTR'):
    '''Find a USB to serial converter and format VISA identifier'''
    tty = find_port.list_devices(vid=vid, pid=pid, vendor=vendor,
                                  serial=serial)[0][3]
    return fmt.format(tty)

Where find_port is in the package: https://github.com/vascotenner/usb-ser-mon/tree/package

Can Lantz provide a more familiar way? Should this be included in lantz? How?
