Not all ports of my MESA boards are visible

Dear Forum
Time to restart working on my cnc, but I'm facing problems, all my apologies in advance if answers are obvious but I missed them anyway
- Fresh clean install of LinuxCNC (2.9.4) with udpates/upgrades done
- a 6I24 connected to a 7I53 (adhoc bitfile)
- a 6I25 connected to a 7I76 and to a 7I74, itself connected to a 7I70 & 7i71 & 7I73
- both 6I's have PC power disabled and 7i53, 7i76 & 7i74 are powered with 5V
-7i76, 7i70 &  7i71 are also powered with 24V (common com), 7I73 not yet ready

Now with preliminary pncconf config to run linuxcnc, when I run readhmid on the 6i25 it seems that I'm missing some ports and I cannot connect them through pncconf: What am I missing ?

Thanks a lot
Emeric

My first guess is that the sserial channels on the 7I74 are not enabled in the hal file
(with a sserial_port_1=00000000 stanza in the hm2_pci driver loadrt line)

Thanks a lot, I will try asap.

Have a great day
