Unable to see Newport ESP301 USB instrument in VISA resource list

I am trying to communicate with a Newport ESP301 controller via USB, using the NI-VISA or PyVISA library.

Here is some information about my machine:

Attempting to use the PyVisa library:

>>> import visa
>>> rm = visa.ResourceManager('@py')
>>> rm.list_resources()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/site-packages/pyvisa/highlevel.py", line 1560, in list_resources
    return self.visalib.list_resources(self.session, query)

    raise errors.VisaIOError(errors.StatusCode.error_resource_not_found.value)
pyvisa.errors.VisaIOError: VI_ERROR_RSRC_NFOUND (-1073807343): Insufficient location information or the requested device or resource is not present in the system.
>>> exit()

Attempting to use the NI-VISA library:

>>> import visa
>>> rm = visa.ResourceManager()
/usr/local/lib/python2.7/site-packages/pyvisa/ctwrapper/functions.py:1225: VisaIOWarning: VI_WARN_CONFIG_NLOADED (1073676407): The specified configuration either does not exist or could not be loaded. VISA-specified defaults will be used.
  ret = library.viOpenDefaultRM(byref(session))
>>> rm.list_resources()
(u'ASRL5::INSTR',)
>>> exit()

Why am I unable to see the USB instrument in the resource list? Any help is appreciated. Thank you in advance.

Have you ensured you configured the NI-backend correctly?

Review these processes:

https://pyvisa.readthedocs.org/en/stable/configuring.html

If you are sure this has been done correctly, consider the following:

Have you been able to communicate with this device before?

Do you have another USB device you could try using to verify the ports and wires are working properly?

Do you have a different machine you could try it on?
