Hi, so steam controller need to add a standalone specific driver to be supported by the OS. But no one from the team have this kind of pad... So it is complicated to add/test it...
If you have linux skills, we can help to build recalbox et add this driver.

Concerning the Xbox one elite pad, it will be supported in 4.1 but only on USB. The wireless adapter is only supported by windows with the official driver from Microsoft. No Linux driver for the moment...

About the extra buttons on this pad, we won't add extra mapping through ES mapping tool. But if the system "see" these buttons, you could customize your retroarch config to use them.
