At this point, BBNorm does not accept multiple input files (other than dual files for paired reads). You would have to concatenate them first:

cat a.fastq.gz b.fastq.gz > all.fa.gz

...which works fine for gzipped files. Most of my programs can accept piped input from stdin, but not BBNorm since it needs to read the files twice.
