From 492ca83c3d19fba1622164f07cd7b775596a7db2 Mon Sep 17 00:00:00 2001 From: Bastien Nocera Date: Tue, 7 Nov 2017 15:24:47 +0100 Subject: HID: sony: Fix SHANWAN pad rumbling on USB The SHANWAN PS3 clone joypad will start its rumble motors as soon as it is plugged in via USB. As the additional USB interrupt does nothing on the original PS3 Sixaxis joypads, and makes a number of other clone joypads actually start sending data, disable that call for the SHANWAN so the rumble motors aren't started on plug.
