No NI device returned by "daq.getDevices"

I am trying to access an NI USB-6001 card in MATLAB.

It is tested successfully in NIMAX. But "daq.getDecives" returns nothing:

>> daq.getDevices

ans =

No data acquisition devices available.

Besides that, I could see "ni" as a vendor in MATLAB, but cannot create an "ni" session, the error message is "Vendor 'ni' not recognized. Use 'daq.getVendors()' for a list of vendors.". See the command line output below:

>> daq.getVendors()

ans =

Number of vendors: 3

Properties, Methods, Events

Additional data acquisition vendors may be available as downloadable support packages.
Open the Support Package Installer to install additional vendors.

>> s = daq.createSession('ni')
Vendor 'ni' not recognized. Use 'daq.getVendors()' for a list of vendors.

Caused by:
    Hardware 'ni' not operational using the Data Acquisition Toolbox.
    Use 'daq.getVendors()' for a list of supported vendors.
    Support for the vendor may require installation of the driver via the Support Package Installer.

Please try to use the "REPAIR" functionality in NI Package Manager to repair the NI-DAQmx driver and see if that helps.
