Game Input MultipleXer

I recently got an xbox one, and I decided to make a DIY adapter. However, once the adapter was finished, I noticed the xbox controllers made after June 2015 are not supported by GIMX.

Are there any solutions to this problem? If not will these controllers work with GIMX in the future?

This is a known issue: https://github.com/matlo/GIMX/issues/336
I can't say for sure when I'll have time to fix this.
