Hi Luis, Many thanks for your prompt and helpfulresponse!
Do you have the relevant DEBUG macros activated in your kernel's configuration?
Perhaps not...
Read this, thanks. But that has nothing to do with KConfigmacros, has it?

If not, activate them. Or if in a pinch, switch to using pr_alert() for development.
What surprises me is that I made sue the message appears inthe .ko file and it was there,whereas it seems pr_debug discards its argument at compile time. Or is it at execution time? Thanks! Sébastien.
