Ozone Strike Battle - Bad Mapping

Hello,

I have recently acquired an Ozone Strike Battle, a tenkeyless mechanical keyboard, when plugged to my MacBookAir with OS X El Capitan the keyboard mapping is a mess. For example:

A maps to H

S maps to Z

K maps to K

The keyboard is detected and worked properly on any other operative system (Linux and Windows) tested. When trying to troubleshoot in Keyboard System Preference panel the keyboard cannot be detected, but activating the option "Show keyboard viewers..." and activating the Keyboard Viewer on the menu bar I can see that while the MBA keyboard is well detected when I press keys from the plugged keyboard the viewer changes to a full keyboard (with numpad included), so my guessing is that this keyboard (and I have found another one that has the same problem) is bad detected and not being mapped properly. Another clue is that the '<' key is mapped to nothing.

Is there any application, or workaround to remap the whole keyboard??

Thanks in advance 🙂
