You can set PCD gEfiMdePkgTokenSpaceGuid.PcdDebugPropertyMask to 0x2F in [PcdsFixedAtBuild] section of Platform.dsc file to enable DEBUG macro. And, set PCD gEfiMdePkgTokenSpaceGuid.PcdDebugPrintErrorLevel to 0x80000040 to enable ERROR and INFO message.

I've enabled the DEBUG macro in my package. I'm using USB_IO_PROTOCOL and I encountered some problems. I want to enable DEBUG macro on all modules that I use in my program. Would you please guide me how I can enable DEBUG macro globally, so I can find the place where problems occur? Regards, Ali
