Here is the information requested:

From Menu:

Debug: Total Power for Royal Flush / Royal Flush was 0.
Debug: Sub-Attack type: /obj/skill/fe_sub_attack/gun/jackhammer
Debug: Sub-Attack type: /obj/skill/fe_sub_attack/gun/jackhammer
Debug: Basic Attack - Weapon Royal Flush; 0
Debug: Total Power for Royal Flush / Royal Flush was 0.
Debug: Critical Multiplier for this attack is: 150%
Debug: no_armor was in flags
Debug: projectile was in flags
Debug: magic was in flags
Debug: no_reduc was in flags

From Hotbar:

This is a bit trickier. If you drag out sub attack onto your hotbar and use it, you will see THIS message once, and only once:

Debug: 0
Debug: Sub-Attack - /obj/skill/fe_sub_attack/gun/jackhammer

Tapping the corresponding hotkey again AFTER that results in this message from there on out:

Debug: 0
Debug: Sub-Attack - /obj/skill/fe_sub_attack/gun

In both instances, the buttons did not allow me to move to targeting, so the weapon could not be fired via the hotbar. I hope that helps.
