Need to discern which HID device inputs are coming from (C# Windows Form)

Question

I'm programming a system which will have several HID devices. Each HID device is intended to input to a different part of the process (program).

Specifically I'll have three bar code readers, one at different parts of a test system, to monitor where a test tray (barcode label) is in a production test.

I need to determine which HID device (barcode reader) an input is coming from so it can be handled appropriately.

Does anybody know how to see which device a keyboard input is coming from?

Answer 1

Does anybody know how to see which device a keyboard input is coming from?

This can be accomplished by handling raw input. For example, see If I have multiple attached keyboards, how can I read input from each one individually?
