I call the scanner a keyboard because that is the way it acts when you

Not really because it always has to be possible to type a code manually 
I've programmed it so that barcode must always start with F2 and end 
with RETURN

Scanners can be programmed to give this kind of header and terminator.

So I don't mind if it comes in all together, It would be nice if I can 
know wich device gives the data but not absolutely needed.

For the moment the scanner is attached on ps/2 with a passtrough cable 
to the keyboard, this works ok but shift and more of those things tend 
to be a problem.
Also I must adjust the send speed of the scanner because it might 
otherwise happen that the computer doesn't get the intire code.

Also we use a lot of macs and (no ps/2) I would like it if the scanners 
are usable on freebsd and mac.

I'm no expert but can't someone port the macos x driver for this (darwin 
is open source and it is also a BSD) ??
