Hi,

I bought a USB to RS232 converter to control my marantz amp via rpi3.

It works with fedora but not working with libreelec(tried with 8.2.5 and latest version) or raspbian.

Anyone have idea?

uname -a:

Linux uurMedia 4.19.3 #1 SMP Wed Nov 21 22:15:07 GMT 2018 armv7l GNU/Linux

dmesg:

Thanks
