Xin-Mo 2nd joystick confusion in Pi2

[kettlehelm]

Hi all,

I had great success in running RetroPie on my old Pi 1 using Xin-Mo dual arcade controllers, and decided to upgrade to Pi 2. The problem is that the 2nd player joystick can’t distinguish itself from the 1st player’s and both are reporting axis +/- 0 and 1 (X & Y). Buttons for both players are working fine.

Here’s my retroarch.cfg copied from my Pi1 to the new Pi2

input_player1_joypad_index = "0"
input_player1_b_btn = "4"
input_player1_y_btn = "1"
input_player1_select_btn = "8"
input_player1_start_btn = "9"
input_enable_hotkey_btn = "8"
input_exit_emulator_btn = "9"
input_player1_up_axis = "-1"
input_player1_down_axis = "+1"
input_player1_left_axis = "-0"
input_player1_right_axis = "+0"
input_player1_a_btn = "3"
input_player1_x_btn = "0"
input_player1_l_btn = "2"
input_player1_r_btn = "5"
input_player1_l_x_plus_axis = "+0"
input_player1_l_x_minus_axis = "-0"
input_player1_l_y_plus_axis = "+1"
input_player1_l_y_minus_axis = "-1"

input_player2_joypad_index = "0"
input_player2_b_btn = "14"
input_player2_y_btn = "11"
input_player2_up_axis = "-3"
input_player2_down_axis = "+3"
input_player2_left_axis = "-2"
input_player2_right_axis = "+2"
input_player2_a_btn = "13"
input_player2_x_btn = "10"
input_player2_l_btn = "12"
input_player2_r_btn = "15"
input_player2_l_x_plus_axis = "+2"
input_player2_l_x_minus_axis = "-2"
input_player2_l_y_plus_axis = "+3"
input_player2_l_y_minus_axis = "-3"

I’m running RetroPie 3.0Beta 2, kernel version 3.18.11-v7, including updated firmware. I’ve double checked for the patch described here and rebuilt it eliminate the rapid joystick movement bug in the new kernel. https://github.com/retropie/RetroPie-Setup/wiki/Troubles-with-the-Xin-Mo-Controller

jstest /dev/input/js0 reports only 2 axis on Pi 2

Driver version is 2.1.0.
Joystick (Xin-Mo Xin-Mo Dual Arcade) has 2 axes (X, Y)
and 22 buttons (Trigger, ThumbBtn, ThumbBtn2, TopBtn, TopBtn2, PinkieBtn, BaseBtn, BaseBtn2, BaseBtn3, BaseBtn4, BaseBtn5, BaseBtn6, BtnDead, BtnA, BtnB, BtnC, BtnX, BtnY, BtnZ, BtnTL, BtnTR, BtnTL2).

The jstest on Pi 1 reports 4 axis (X, Y, Z, Rx)

Anyone have any suggestions on how to fix this problem and distinguish the two joysticks?

Thanks!

ps. My Pi 1 is running RetroPie 2.6.0 and kernel v 3.6.11

Resolved it by reverting back to 2.6 and using feederchain’s suggestion here:

Autofire on the axis
