The problem was, even though i had gpiopps_load="YES" in my /boot/loader.conf, and the module was loaded during boot -- it was NOT creating anything in the /dev/ folder. Same was true for a uftdi_load="YES". Even worse, if I built the ftdi module into the kernel, the system would not boot for some reason. So I did what felt quite logical (after reading all the supporting emails you have sent me, thank you so much). I unloaded and re-loaded the kernel modules, and lo! all the devices popped up like magic :D And now I wrote a small script to wait a few seconds after boot, and then unload whatever has been loaded, and then load only the ones I need. Working like a charm! Thanks to everyone, once again, for helping me to make it work. Best regards
