Warning: unrecognized item "timeout" in "qSupported" response

Well in theory the library should only use up one serial port and leave all others intact…

jdolinay/avr_debug/blob/master/avr8-stub/avr8-stub.h#L233-L244


      
          * Supported values for Atmega2560 and Atmega1280:
          * 0 - use USART0 (Arduino Serial cannot be used with the debugger)
          * 1 - use USART1 (Rx=PD2=D19, Tx=PD3=D18)
          * 2 - use USART2 (Rx=PH0=D17, Tx=PH1=D16)
          * 3 - use USART3 (Rx=PJ0=D15, Tx=PJ1=D14)
          * 
          * Note: the number in AVR8_UART_NUMBER is used to generate register names in macros; 
          * don't put it into parentheses.
          */
          #ifndef AVR8_UART_NUMBER
                 #define AVR8_UART_NUMBER       0
          #endif

There might be issues with how the Arduino core is written and if serialEvent3 is defined then it has an influence on other serial ports…

Can you minimaly reproduce this issue of it non-working with the How to debug on Arduino mega 2560 - #2 by maxgerhardt project but an added void serialEvent3() { }? If yes, report that to Issues · jdolinay/avr_debug · GitHub.
