Be sure to use the "House of the Dead 2 Config" program to set both Player 1 and Player 2 inputs to "Keyboard". The Troubleshooter disables mouse input in the game and sends simulated keystrokes to make it fire and reload. So if Player 1 is set for mouse input (which is the default), then you'll get the exact situation you're decribing.
As for MAME, the most recent versions of MAME seem to no longer support the dual TV guns. I don't know if this is temporary (i.e. a bug that needs to be fixed) or if they decided to remove that functionality permanently. I can't seem to get anyone on the MAME team to respond about that. The best I can suggest is to use an older version of MAME or MAME32. Version 0.84 is the last working version I know of.

Hey all. NEWBE here.
Anyways, I receved my new Act Labs TV out light guns about 2 weeks
ago.
The prob that I am having is with HOTD2 I can only get one player at
a time to work. I have tried the trouble shooter. If I use it, it
shuts off player 1. Without it, I can not get player 2 to work.
Under Mame32 I can get player 1 to work fine, but I can not figure
out how to configure the controls to get it use player 2's gun. I
can get the fire button to work but I can not figure out how to get
it for aiming.
As far as software versions Mame is .89 and HOTD2 is Activion Value.
Any help or ideas would be great.
John
