Cannot configure 2 different controllers which have the same name

First of all, I am not sure if this issue is really related to the Retropie-Setup itself.
It is actually related to the configuration of controllers in EmulationStation and retroarch.

Currently the controllers are identified by their name (name attribute given by udev).
However, I happen to have 2 different types of gamepads which firmware is made by the same company (while the brand of the gamepads are different), so their udev name is the same ("USB, 2-axis 8-button gamepad ").

However, the physical disposition of the buttons is different, which means that if I configure one of the gamepad, the other one will have the buttons A swapped with B and X swapped with Y.

I tried to fix the issue with the following methods:

• Remap the buttons of one controller using jscal and jscal-store. However, since EmulationStation and Retroarch relies on udev, this solution does not work (I tried to change the input driver from udev to linuxraw, but the result was the same)
• Try to change the name of the devices with a udev rule (what a fool I am). I realized this is impossible...

But I do see one solution, which would be to use the Product and Vendor ID or GUID in addition of the device name.
This solution currently works in EmulationStation. If I add the DeviceGUID in addition of the device name, I can have 2 different settings for controllers having the same name.
So it would be nice that the DeviceGUIS would not be stripped off in the es_input.cfg.

The remaining task would be to make Retroarch compatible with another way to identify the controller.

Start by reviewing how EmulationStation writes controller entries to es_input.cfg and whether DeviceGUID is stripped. Then trace how RetroArch identifies controllers and compare the udev, linuxraw, jscal, and jscal-store paths mentioned in the issue. Done means distinct controllers with the same name retain separate mappings in both EmulationStation and RetroArch.
