Problem FW LimeSDR mini

It seems to me that the problem is in FW. Here are examples of messages from Livesuite: [18:13:03] INFO: Connected Control port: UNKNOWN FW:0 HW:15 Protocol:0 GW:0.0 RefClk: -0.00 MHz [18:25:38] Port opened;
[18:25: 38] ERROR: Communication error.
[18:35:38] ERROR: Error initializing serial port. Thus, the serial number is read correctly. What are the options for solving the problem? I can 't find the FW version for LimeSDRmini.
