I can't see SysIntr value in Your registry settings. Probably
SysIntr value is hardcoded in the driver. Please check Your
driver code and OEMInterruptXXX routines to see
if there is support for FFUART interrupts. Also
check Your driver code where driver object is
really created. I think it should be something like
switch (DeviceArrayIndex)
{
case 0: pDevice = new CSTUart(...); break;
case 1: pDevice = new CBTUart(...); break;
case 2: pDevice = new CFFUart(...); break;
}
... and verify if FFUART has array index "3"
since You use "DeviceArrayIndex: 3" in registry.
