I'm sorry and promises to improve 
@Mariusz
In my case the solution was in MyConfig.h file (in my case C:\Program Files (x86)\Arduino\libraries\MySensors):
-
Disable function MY_DISABLED_SERIAL
commenting lines 49
// #define MY_DISABLED_SERIAL -
Disable function MY_DEBUG
commenting lines 36
//#define MY_DEBUG -
Correct connection is on my pictures enclosed in the above comment
Board | Transmit | Receive | PWM Unusable
Arduino Uno | 9 | 8 | 10 <----- Form https://www.pjrc.com/teensy/td_libs_AltSoftSerial.html .... (& other ATMEGA328)
Arduino Leonardo | 5 | 13 | (none)
Arduino Mega | 46 | 48 | 44, 45
DE and RE -> Pin 2
RO -> Pin 8
DI -> Pin 9

To check the hardware and connections run the "Example Program" from https://www.pjrc.com/teensy/td_libs_AltSoftSerial.html
-
Use development branch
