USRP_N200 unable to connect via vmplayer

I have vmplayer virtual machine running on my computer as my system is
partition style and which is not taking dual boot of any release of

I connect to an ethernet port to a USRP rx… and do a uhd_find_devices

it says no device found… although I have a valid gnuradio distro +uhd
my computer and it works fine when I am not using the USRP though…

Could it be because of the vm that I am using? Please suggest what do I
need to do!!

this is my eth0 config-

eth0 Link encap:Ethernet HWaddr 00:0c:29:23:94:4e

This shows up when I am doing my firmware update-

You’re sure its not at the default address

Don’t know if you have the same problem but I use a USB to GigE adapter
from vmware player and I found that it ONLY works if I boot the VM with
the interface that is connected to the USRP as the only active network
connection. I can enable the network interface to the host OS after I
boot and it still works but for some reason if the VMnetX interfaces are
active at boot it messes up the ability to find the USRP.


Check if your usrp is surely on Run uhd_usrp_probe and
check if it is giving any output. Do you have gigabit ethernet card on
laptop. If not, you will have to use a switch in between and some times
switch might be an issue.

one more thing, are you connected on static ip? If you are on dhcp,
it to static ip and see.

  1. I tried using vm bridged connection over NAT… i assigned
    and subnet in the ubuntu network setting running on
    vmplayer… I am pretty much sure about the other USRP IP since… i used
    some other machine to do uhd_find_devices … so check for their IPs…
  2. My ethernet port is working fine on windows… I though did not check
    on my vm… bt hopefully it is working since it is recognizing the LAN…
  3. The sw is perfectly fine tested OK.
  4. I changed it from dhcp to manual ipv4 settings as 1. the problem
    persists… the device is on…
    i did uhd_usrp_probe with --args=… it says the same.
    could not find devices…

I feel there is a big issue with the vmplayer network settings with

Well, can you ping the USRP from the VM? That would eliminate the
question of uhd and UDP sockets.

Can you ping another device with a static IP though the VM, like a
router that is connected to the same network interface as the USRP?
