Way to solve libuhd error message output with USRP B210

When I try to run any Simulink model or script using my USRP B210 device, I got an error message of libuhd. What does that mean and how can I solve it? For better understanding please find attached screen shot of the error message. Any help would be appreciated greatly!

In order to fix this UHD error, kindly update your UHD driver for the USRP hardware from the driver link:

http://files.ettus.com/binaries/uhd/latest_release/

Steps: -

1. Download the driver from above link for your win 32/64 bit. But, download the latest release VS2015 for your OS.

2. Open MATLAB and Connect your USRP hardware with PC.

3. Now install the UHD driver - After installation, close your matlab and remove USRP device.

4. Open MATLAB and connect USRP device with PC

5. Finally, run the findsdru in command window and make sure it's a success.

For more details, refer to the verifying the MATLAB connection to USRP doc link and also common problems and fixes:

This did not work for me. After following the instructions, the following results from findsdru:

I have the same problem. Have you made any leeway?
