I'm not sure what you mean by:

everytime i try to put the file extension into the terminal

Can you please explain exactly what you're doing?

okay so the crazyflie demo on the cylon.js site, I copy and pasted it into a notepad program and i named it as test.js , everytime i try to run test.js in the terminal(type in test.js in the terminal to run it) it says "Command does not exist" or "No such file or directory"...

I see. What "notepad program" did you use? It might be saving the file as something other than text and just changing the extension to '.js' won't help that. Also, your file is not executable. You need to run it by passing it as an argument to node. Type "node" into the Terminal and then drag the fie to the Terminal.

But, all of this will be moot because it won't work anyway specifically for the reasons listed in the thread above. Unless of course you have a very old nodejs install (like 0.3.11 or older).

Good luck!

With all due respect natekicksa, there's nothing more annoying than a question that shows you haven't even read the thread you're replying to. This has already been answered here.

The version of node-usb that works is too old to work with the current nodejs releases. To use a working node-usb module you have to downgrade to nodejs 0.3.11. This is quite the downgrade from 4.2.4 and most people doing this would likely not want such an old release. If you do not mind, have at it then.

I also tried to simply install an earlier version of node-usb but that cause npm to throw a bunch of errors I didn't want to look into. I don't think that's a viable option unless you downgrade node as well, which is likely a non-starter as well.

sorry about that chad, i was just curious. thanks for your help

fyi, I was just working on a node-usb version of the radio driver and ran into a similar problem with lib_usb. I think you need to downgrade to node 0.12.7 if you haven't already and then re-run npm install. try the n node version manager if you haven't yet? https://github.com/tj/n
