Patch to make reading the controller buttons work

[awesomebytes]

To workaround #27 on my Ubuntu 16.04 64bits.

I admit it's ugly but it makes it work on my system.

Also, find a minimal example that prints all the controller events on the terminal:

Even if it's not mergeable, I hope it helps someone to get this to work.

Hi, I agree this might not be the most clean solution but I also think there is no other choice.

Please bear in mind this __init__.py file is generated with the translate/translate.pl script. But quoting cmbruns:

Ideally we should add a rule to translate.pl to catch this situation. But because I don't have much time to look at this now, it would be OK to manually patch init.py, with a big "TODO" comment, like I did in several other places where I manually carry forward edits into subsequent releases.

So if you add a TODO like that I would be +1 for merging, for whatever that's worth :)

Since you are on Linux, please also keep in mind there are more situations where struct packing requires some 'hacking': You can search on "Terrible Hack" in openvr's C# bindings to find where they applied the hack. (Properly fixing all that is I think part of #35).

@daniel5gh I added a commit with the big TODO as you requested. Thank you for following up.

Any chance to merge this? :) Thank you.

@cmbruns thank you! and thank you for re-releasing :) This is powering my ROS wrapper for the HTC Vive.

You are welcome.
