Much better.  Now the STATUS and CONFIG replies are there.

Next time "-v 2" makes it esier to read.

Notice this:

    UBX-MON-COMMS:
    version 0 nPorts 5 txErrors x0 reserved1 0
    protIds 0x0/1/5/ff (UBX/NMEA/RTCM3/None)
      Port: 0x100 (UART1)
       txPending 0 txBytes 73334073 txUsage 2 txPeakUsage 99
                                              ^^^^^^^^^^^^^^

Overloaded tx buffer.

You also appear to be using ports 0x200, 0x300, 0x101 and 0x201?
What for?  How?

Overflowed tx buffer on UART1.  YOu might find the USB port works
faster.  Or not.

How did you enable the subframes?  And I do not mean UBX-RXM-SFRBX
subframes.

You can see all your output messages enabled this way:

$ ubxtool -g CFG-MSGOUT,0,0,1200  -P 27.10
