Actually the problem is probably within the CPLD.
Irrespective of the CPLD register LUB_IRQ_MASK_EN, the GPIO0 is always low,
indicating an interrupt all the time.

The only thing that changes that is the switch SW13, which forces GPIO0 to high,
but prevents interrupts.

Normally, GPIO0 = (SW13 | ! (LUB_IRQ_MASK_EN && LUB_IRQ_SET_CLR))

This is why I don't have any interrupt, next stage will be to verify U46 and U54
on the IO board for GPIO_INT# and USB_INT# signals ...

Cheers.
