Xbox 360 controller not recognized anymore

Hi, I updated RetroArch nightly yesterday evening, and the joypad profiles too. My xbox 360 controller is now recognized as an Arcade Pad (Mad Catz BrawlPad). This is problematic because the controls are now messy. To fix this I reinstalled the 1.8.9 version, but as a result, my controller is recognized as EasySMX. This is problematic too: I can only map 2 buttons (A and B). Next, I re-updated RetroArch nightly, re-updated the joypad profiles too, and I have the same bug : Mad Catz BrawlPad instead of xbox 360 controller. I want to fix this, isn’t there a way to edit the joypad profiles directly, what should I check ? Because even if I remove the Arcade Pad (Mad Catz BrawlPad).cfg file in the xinput folder, this change nothing… My controller is blocked with the Mad Catz association.
