I had a similar issue with E310/E312s recently on Ubuntu 20.04. USRPs and host computer were set up with static IPs on the same subnet, could ping and SSH into radios but uhd_find_devices returned no devices found. Turns out it was an issue with Ubuntu's
firewall. I had to turn off the firewall in order to get it to work.

Subject: UHD device not found
Hi,
I am having a USRP N320 and installed gnuradio+uhd (4.0 version) on ubuntu 20.04 LTS. Earlier, device is working fine with following command-
Ping 192.168.10.2
uhd_find_devices
uhd_usrp_probe
But, now I am using it after some time, and the device is pinging properly. However, when I am running the command
uhd_find_device, it shows no device found. So help me regarding this issue.
