[srslte-users] Error with USRP b200 mini

[Iulia Gudovan]

Hello!
I'm using USRP B200mini-i and I have a similar problem. Even if I set
nof_ports to 1 in enb.conf, I still get Error opening UHD: code 11 /  error
opening rf and can't run anything. After this, if I run uhd_find_devices or
uhd_usrp_probe it says there are no UHD devices found, even if the LEDs on
the USRP are on and the device was detected just moments ago when launching
the eNodeB... What should I try?
