Hey Guys...

After a LOT of reading up... (that amounts to more than a paragraph for me...LOL) ... I have come across `node-hid` ... Managed to get it installed, but now need to find out how to use it from `Node-Red` ....

The initial bits seem to work:

```auto
$ npm install -g node-hid
$ hid-showdevices libusb
$ hid-showdevices hidraw

```

I can see from a terminal session the addition or removal of a hid device, so things are talking in the background....

_ **Crunch** _ .... That's where my knowledge ends....

The little bit I did with a crc16Xmodem function node kinda lets me think that I can incorporate the hid functions in a similar manner, but way I'm out of my comfort zone....

I think I am on a "possible" track, but hey.... Does anybody have a gps and a white stick to lend me?
