A common problem for usesrs is attaching additional input devices (eg. touch panels, keyboards, ...), to LV-based systems (including embedded controllers), but yet LV seems to miss an generic API/binding for that.
In Linux world (and BSD, too) we have standard APIs for that. On kernel side, there is evdev, which has lots of drivers for quite any kind of input devices you could buy (and easy to extent for new, even selfmade devices). In userland, there's an small wrapper library - libevdev - which encapsulates the platform/kernel specific stuff and is easily portable to other OS'es (eg. there's already a BSD port, Win32 and MacOS ports shouldn't be a big deal either).
This library could be directly called from a VI. This VI could also exist in several specific (and potentially highly optimized) versions, to Labview users have a generic API handling input devices (such as standard USB HID class) in LV.
