There seems to be a number of subtly different firmwares for the Playstation controllers made by "Gasia Co.,Ltd". Whilst such controllers are easily detectable when attached via USB that is not always the case via Bluetooth. Some controllers are named "PLAYSTATION(R)3 Controller" where as the official Sony controllers are named "Sony PLAYSTATION(R)3 Controller", however some versions of firmware use the exact name used by the official controllers. The only way I've been able to distinguish these versions of the controller (when connected via Bluetooth) is that the Bluetooth Class of Device incorrectly reports the controller as a keyboard rather than a gamepad. I've so far failed to work out how to access this information from a HID driver. The Gasia controllers need output reports to be configured in the same way as the Shanwan controllers. In order to ensure both types of Gasia firmware will work, this patch adds a quirk for those devices it can detect and reworks `sixaxis_send_output_report()` to attempt `hid_hw_output_report()` should `hid_hw_raw_request()` be known to be the wrong option (as is the case with the Shanwan controllers) or fails. This has got all the controllers I have working, with the slight anoyance that the Gasia controllers that don't currently get marked with a quirk require the call to `hid_hw_raw_request()` to fail before the controller finishes initialising (which adds a significant extra delay before the controller is ready). This patch is based on the following patch by Conn O'Griofa: https://github.com/RetroPie/RetroPie-Setup/pull/2263/commits/017f00f6e15f04b3272ff1abae8742dc4c47b608 Cc: Conn O'Griofa <connogriofa@gmail.com> Signed-off-by: Martyn Welch <martyn@welchs.me.uk> --- drivers/hid/hid-sony.c | 31 +++++++++++++++++++++++++------ 1 file changed, 25 insertions(+), 6 deletions(-)
