No such messages here, in 2.3.39 or 2.3.40.

I presume this is the relevant piece of code?

   1568     case PPCPIA_PARPORT_AUTO:
   1569         if (port->probe_info[0].class != PARPORT_CLASS_MEDIA ||
   1570             port->probe_info[0].cmdset == NULL ||
   1571             strncmp(port->probe_info[0].cmdset, "CPIA_1", 6) != 0)
   1572                 return;

Nothing. Umm. I'm installing the camera in a Windows box to see if it
is working properly (which I suppose it is). If the camera is OK, perhaps
something bad happened to my parallel port. Ouch.
