From: Marcel Hasler Date: Thu, 3 Nov 2016 18:47:42 +0000 (+0100) Subject: HID: Add new force feedback driver for Mayflash game controller adapters X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f8690450f3d0d415f42c94f7e69258d8ba54ff29;p=linux-beck.git HID: Add new force feedback driver for Mayflash game controller adapters Add a new module named hid-mf that implements force feedback for game controller adapters manufactured by Mayflash. Currently only the PS3 adapter is supported, other adapters still need to be tested.
