XPS3 and WSA12

[famous58]

I just installed a XPS3 and a WSA12 right next to each other.  The XPS3 was working fine (remote/PC) and the WSA12 was not working.  Now the WSA12 is working and the XPS3 is not (the switch itself works, but I cannot control with remote/PC). 

After searching through these massive forums for about 30 minutes, I see nothing that would lead me to a solution.  Anyone have any ideas or am I relegated to some "read the FAQs" posts?

T.I.A. (I hope).

Maybe a wiring problem. If you turn one on does the other start acting up?
What are the loads on each switch. Like motor; fan; regular; bulb CFL etc.?
