Apparently, the Virtualbox is not recognizing the Ettus N320!
Looking forward to your kind advice.

Hello Thangaraj,
you need to check the IP-Address of the virtual machine. There’s two
different addresses for each SFP on the USRP device. They are
depending on both the port and the speed. On mine (X310) they are
192.168.10.2 for the 1GBit/s and 192.168.30.2 or 192.168.40.2. I
guess it is the same with yours. You can first try to ping the device
both on the host and the VM.
Best Markus

Your PING example is pinging the IP address of the host, NOT the USRP
N320. This will always succeed.
You'll need to change the IP address of that network interface to
192.168.10.1, so that it is on the same subnet as the USRP N320 default
address for the SFP0 port
of 192.168.10.2.
