Comment 4 for bug 1419563

This is not a bug. The keyboard chipset uses a non-standard protocol to support n-key rollover. I wrote a driver for it. You can download it from https://bitbucket.org/Swoogan/aziokbd

I wrote a blog post about implementing it, ending with: http://swoogan.blogspot.com/2014/09/azio-l70-keyboard-linux-driver.html

Let me know if you have any issues with it.
