I can confirm the 2 buttons on the lindbergh itself does not work with every game. In the game that did work was Virtua Tennis 3. I tested all of the Virtua Fighters and none of them work with those buttons nor the ones on my super gun. I did get a tip from someone outside of here on the exact jvs I/O board to get but yeah, my naomi 2 jvs to jamma does not work. It does work in the multi menu but only down and start. My thing is, since my cab is jamma, I have to find away to make some harness that goes into the new sega I/O I have to buy and convert that to jamma or somehow make my cab a jamma/jvs hybrid but I am not super adept in the JVS which that will be a learning curve for me.Make sure the IO is appropriately powered, but regardless of that, there are 2 buttons on the motherboard above the PIC slot. Using these you should be able to navigate test menus etc. You can probably fumble thru the menus to find JVS IO info/tests for your IO to see if it's even being seen.
