Mame: game not recognizing keyboard keys when launched from LB

Cab keys that are controlled via an ipac kb controller are not recognized by Centipede, when launching the game through LB.  Other games work as expected.  The start and coin keys are not recognized by a physical keyboard either.

Launching Centipede directly from Mame (same config used in LB) works as expected (arcade cab keys are recognized).  

Funny thing is that Millipede (as well as other games) don't exhibit this behavior and are using the same Mame config as Centipede.

Any ideas?

update: (1) physical keyboard works as expected whether going through LB or Mame.

(2) changing "-keyboardprovider dinput" to "-keyboardprovider raw" solves the key issue, but doesn't trigger a "pause", like it does when set to "dinput"

 

I can live without using pause screens for a specific game, but am still interested in a workaround, if anyone has run into this.

Launch Centipede, press Tab, select Input Settings, then Input Assignments.  From there, set (reset) the Player 1 Start, Coin 1 and Coin 2.

Alternately, delete /cfg/centiped.cfg  This most likely is holding remaps to the key inputs.

Launching directly from MAME, both keyboards are recognized, and work as expected.  From DOS prompt, entering "mame -keyboardprovider dinput {name of rom}" works as well (both keyboard and cabinet keys are recognized).  

If i launch to MAME (screenshot above of config) from LaunchBox, only one keyboard is detected.  My cabinet keyboard does not register keypresses in MAME.

In both instances, i'm running from the same MAME folder.

Troubleshooting further found that LEDBlinky seems to be interfering in some way.  If i disable it, the ipac controls work as expected (just like when launching directly in MAME).  If I re-enable LEDBlinky, i can't get any of the ipac keys to register (the attached keyboard works fine though).
