It turned out that there was some hardware problem. Other USB devices didn't work either and the Rii worked fine in another Pi. Changing OS didn't make any difference. After replacing the Pi2 the Rii did work again.

I am using two Pi's with Rii mini i8 keyboards. One Pi3 and one Pi2. Both keyboards/dongles work fine on the Pi3. The keyboard/dongle do not work on the Pi2. There is no information about the USB-ports in the log-file.
What is going wrong and how can I get the keyboard working?
Or how can I find any issues?
Below information about the Pi2's USB-ports:

- Switching USB-ports for the dongle.
Doesn't make any difference. Device 4 is not visible and the other ports don't show the dingle. - Switching keyboard and dongle between the Pi's.
Both keyboards and dongles work fine in the Pi3. - The dongle in the Pi3 has MxPwr=100mA
The other ports supply between 0 and 2mA. Maybe the Pi2 ports cannot supply power at all. - There is no data in the log-file when I switch USB-port on a running system
- I think the keyboard worked before I upgraded to Libreelec 8.0.2
I am not sure if this was the moment the keyboard start failing. The keyboard has worked on the Pi2.
- Switching USB-ports for the dongle.
