I'm using DVBSky S960 USB SAT receiver on RPI3B with Libeelec. It generaly works fine until following lines appear in dmesg output:
Since that nothing but hard restet (power off) receiver and restart Libreelec can help.
I did some searching over Inet and found 2 solutions:
1. replace power supply (I did but without any special results)
2. install new firmware (don't know how to do it on Libreelec)
Any help appreciated
