I have a USB device I want to use as a pendant which has an LCD display.
I'm OK with writing the USB code to program it, I'm just unsure how I can
integrate it with emc to provide useful outputs.  

I'm building yet another "joystick" type hal component.  It works at a lower
level allowing access to all HID items - it should work with the ShuttlePro.
Initially I was thinking my hal component would have a pin that was a string
input, but hal doesn't support that.  Is there another standard way to
communicate strings?  I'm not sure if I need to expose that interface to
other hal components.  My component will live in user space.  Maybe I just
need to be to talk to axis.

Any thoughts?
