It may work with your NIT, but without a model number, it's hard to know. If you post which model of keyboard you have, I'm sure one of our forum members can look into it for you. As for the USB control app, that may not be what you need; if it is an HID-compliant USB keyboard (as are desktop keyboards), then that should be all that is needed, as far as I know (correct me if I'm wrong - I haven't tried it), however, given that it is intended for Palm handhelds, it may well work completely differently. In that case, you would probably need a driver for your keyboard model - so again, we'd need to know what that is.
Let us know...
