Physical Channel.do_port_width fails for ports of width 1

Physical Channels with width 1 give errors when querying the port width. This is e.g. an issue for the NI device USB-6001 (named in our case "USB_6001_1") on PORT2 with width 1. However, the port can be read correctly by system.devices[].do_ports, but its width cannot be queried.

See code below:

import nidaqmx.system

system = nidaqmx.system.System.local()
print(system.driver_version)

for device in system.devices:
    print(device)
    print(hex(device.serial_num))
    print(device.terminals)

    print(device.ai_physical_chans.channel_names)
    print(device.ao_physical_chans.channel_names)
    for do_port in device.do_ports:
        print(do_port)
        print(do_port.do_port_width)
    for di_port in device.di_ports:
        print(di_port)
        print(di_port.di_port_width)

Output is then:
