It cannot print the names of empty files. Empty files have no lines, so no code is ever run for them. You can easily check those yourself after:

Code:
awk ... > output

for FILE in data/*
do
        [ -s "$FILE" ] || echo "$FILE,0,0"
done >> output

       -h     displays this help and exit

       -v     output version information and exit

       -d     print contents of received events to standard error

       -s     terminate program when a SIGPIPE signal is received.  The default is to ignore SIGPIPE.

       -e BUTNR
	      only generate mhub events for buttons >= BUTNR.  The default is 4.

       -b FILE
	      output mhub events to FILE

       -2 FILE
	      output PS/2 format data to FILE

       -i FILE

       -m FILE
	      output MouseSystems format data to FILE

       -r FROM TO

       -w BUTNR
	      transform wheel up motion to a BUTNR mhub event

       -W BUTNR
	      transform wheel down motion to a BUTNR mhub event

       A maximum of 20 mhub event outputs and 20 mouse data outputs are supported.  The number of remaps are unlimited and all remaps occur before
       any other processing.

       Mouse data outputs may all use different protocols.
