Now my Byteblaster2 is running with my PCI parallel port adapter. The problem was during QuartusII installation the field "DependIOnService" of AlteraByteBlaster (HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\AlteraByteBlaster) in Windows registry was filled in to be dependent from service "parport". When I installed my PCI parallel port adapter (MosChip chipset) the service installed to take care of parallel port was NmPar. Since I pointed "DependIOnService" of AlteraByteBlaster to "NmPar I dont have problem using Byteblaster2 anymore.

Thanks wmrsouza, you just saved my tearing my hair out in frustration. I have Parallel port PCI add in card based on a MosChip device.

For reference:

My port is LPT1.

Is NOT at any of the old standard addresses (278, 378 or 3BC).

I do have 'Enable Legacy Plug and Play detection' ticked in device manager but I have not tested if that is necessary yet.

I have ‘Never use an Interrupt’ ticked in device manager.

I changed the reg key as you suggested, rebooted and the byteblaster became usable :-)
