Hi!. When I have to use my X310, executing the command "uhd_usrp_probe" I obtain the following message:

After that I run twice this command, all the warnings disappear and I can use the board. If I switch off my linux box and I restart all, the command "uhd_usrp_probe" produces the same warnings how reported here. There is a way to "hard write" in the linux box this configuration command to avoid every time to check if the board is ready or not? My linux box is: Ubuntu 16.04: uname -a : Linux name-linux-box 4.4.0-103-generic #126-Ubuntu SMP Mon Dec 4 16:23:28 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux Thank You.
