Hello I am trying to setup OpenLTE. My system specs are Core I-7 with Ubuntu 16.04 and USRP B205mini but I have USB 2.0 connectivity supported in my CPU. When I start openlte i see following debug logs and application exits. Logs are attached in file Trying 127.0.0.1... Connected to 127.0.0.1.

Why is it so? Is it due to lack of USB 3.0connectivity? but in next logs, I can see that its actually getting the required clock rate. Then what could be the reason for failure in stable start? $ sudo LTE_fdd_enodeb [INFO] [UHD] linux; GNU C++ version 5.4.0 20160609; Boost_105800; UHD_3.11.0.1-16-g34fc6362 *** LTE FDD ENB *** Please connect to control port 30000 [INFO] [B200] Detected Device: B205mini [INFO] [B200] Operating over USB 2.
