Hello. I haven't used it at all, so it's all just speculation....
After looking at devd.cc for about 5 seconds, it doesn't seem like the conf for devd is being reloaded within the event_loop. It seems that if a new conf for devd is installed, devd must be restarted. I still do not know if that is correct :) webcamd at my environment is working properly :) If devd is working correctly, it seems that tpm2-abrmd-devd.conf will function properly when the tpm0 node is created. It does not work properly for tpm1 :) Isn't the part written as /dev/tpm0 supposed to be /dev/$cdev ? I was concerned about that part, so I'm writing it down for now :) Regards.
