I don't have sixpair on my system, so what I did was simply replace the line:

my @sixpair = qw(sixpair >tmp1); with
my @sixpair = qw(lsusb >tmp1);

to see what would happen. The window successfully got the output of the lsusb cmd.
I would check to see if your 'sixpair' system cmd is actually being called. I suspect it is failing, with the
failure going to the terminal and never getting to your tmp1 file.
That is what is happening to me anyway.
Hope that is helpful...

...the majority is always wrong, and always the last to know about it...
Insanity: Doing the same thing over and over again and expecting different results.
