What you are trying to do is seperate the two devices so that the
keyboard is processed normally while the other device is processed
independently, perhaps more like a serial device. This way you can
programmatically process whatever comes from this other device
instead of having it look as though the user typed in something.
Although writing its own driver does solve this issue, doing so is
a project in itself. Before looking into this option I would evaluate
costs for other options, like:
a. Checking with the device manufaturer to see whether the device
is programmable and a certain behavior can be assigned to it (ie, make
it look like a serial port, not a keyboard).
b. Considering costs, get another device that will satisfy this need.
c. Redesign UI to handle KB emulating device.
I agree in that you need certain considerations when designing a UI
that allows a secondary input device (scanner, barcode reader, etc.)
so that it won't wreak havoc with the user and option c in my opinion
is the least desirable, but even even less desirable is the option whose
cost is prohibitive (time, money, resources, etc).
Best regards!
