Hi all, just to conclude on this problem, compiling sigrok from source solved the problem:
$ sigrok-cli --scan sr: ftdi-la: Failed to get the FTDI strings: -4 sr: ftdi-la: Failed to get the FTDI strings: -4 The following devices were found: demo - Demo device with 13 channels: D0 D1 D2 D3 D4 D5 D6 D7 A0 A1 A2 A3 A4 kingst-la2016:conn=1.18 - Kingst LA2016 with 18 channels: CH0 CH1 CH2 CH3 CH4 CH5 CH6 CH7 CH8 CH9 CH10 CH11 CH12 CH13 CH14 CH15 PWM1 PWM2 Thanks to Dennis Dingeldein for the advice.
