Hi Stef,

I did as you proposed, making sure to save the file and run make after 
each change. There were 5 occurrences of DGB_io2 in that context and 
even changing all of them did not fix the problem.

I also did the same for 17 occurrences of DBG_io, but no fix.

make did seem to detect the changed file and recompile it after each change.

This is with export SANE_DEBUG_GENESYS_LOW=6 set in the runit script. 
Setting it to 7 and the problem is gone and I get reliable scans.
