DVBSky S960 USB failed=-110

Hi

I'm using DVBSky S960 USB SAT receiver on RPI3B with Libeelec. It generaly works fine until following lines appear in dmesg output:

[4952.874220] usb 1-1.2: dvb_usb_v2: usb_bulk_msg() failed=-110
[4952.874235] usb 1-1.2: failed=-110

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

Directly attached (e.g. without the hub) the messages disappeared and everything was working as expected.

How is your setup? If you also have an USB hub maybe this could be worth a try.

It's connected directly to RPI....

Bit wired that MAC is always ff:ff:ff:ff:ff:ff .....

Here I can find fw version = 3.B. How about yours ?

Firmware is the same 3.B
But mine shows a valid MAC address...

To be honest I don't have an idea what might cause this issue, just wanted to share what helped me.
Anyone else here who can help?

Thanks - I know now that I have working fw and set up
Maybe somebody else could help me ...

Finally all works fine !

Tip for others:
I replaced my power supply for both RPI and DVBSky. Since that time no error occurred.
