Setting up a USB gamepad on FreeBSD

P

Hello,

I have a cheap but cool Thrustmaster gamepad and I want to use it for playing games in FreeBSD emulators. I tried to configure it but I really don't now very much about this process. Here is what I've done.

  1. I installed xf86-input-joystick and uhidd from ports
  2. I added these lines to rc.conf:
    Code: 
    uhidd_flags="-kmohs"
uhidd_enable="YES"
  3. When the gamepad is plugged in, the kernel said:
    Code: 
    uhid0: <Mega World USB 2-Axis 8-Button Gamepad, class 0/0, rev 1.10/1.01, addr 3> on usbus1
    so it seems like the gamepad is seen by uhidd
  4. I added these lines to xorg.conf:
    Code: 
    Section "ServerLayout"
	Identifier     "X.org Configured"
	Screen      1  "Screen1" 0 0
	InputDevice    "Mouse0" "CorePointer"
	InputDevice    "Keyboard0" "CoreKeyboard"
	[B]InputDevice    "Joy0" "SendCoreEvents"[/B]
EndSection

Section "InputDevice"
    Identifier     "Joy0"
    Driver         "joystick"
    Option         "Path" "/dev/uhid0"
    Option         "Device" "/dev/uhid0"
    # Right Buttons
    # Button w(Up)/s(Down)
    # Button a(Left)/s(Right)
    Option         "MapAxis1" "mode=accelerated keylow=38 keyhigh=40"
    Option         "MapAxis2" "mode=accelerated keylow=25 keyhigh=39"
    # Right joystick: Like mouse
    Option         "MapAxis3" "mode=relative axis=+1x deadzone=5000"
    Option         "MapAxis4" "mode=relative axis=+1y deadzone=5000"
    # Left joystick: 
    # axis X - Left/Right
    # axis Y - Up/Down
    Option "MapAxis5"       "mode=relative deadzone=28000 keylow=100 keyhigh=102 axis=0.15key"
    Option "MapAxis6"       "mode=relative deadzone=28000 keylow=98 keyhigh=104 axis=0.15key"
    #
    Option         "MapButton1" "key=10"
    Option         "MapButton2" "key=11"
    Option         "MapButton3" "key=12"
    Option         "MapButton4" "key=13"
    Option         "MapButton5" "key=14"
    Option         "MapButton6" "key=15"
    # mouse button: left
    Option         "MapButton7" "button=1"
    # mouse button: right
    Option         "MapButton8" "button=3"
    # button "Space"
    Option         "MapButton9" "key=65"
    # button "Enter"
    Option         "MapButton10" "key=36"
EndSection
    [/lit]

    The current behavior: xev doesn't show any event when the gamepad buttons are pressed.

    The Xorg.0.log joystick part here:

    Code: 
    [    52.975] (II) Using input driver 'joystick' for 'Joy0'
[    52.975] (II) Loading /usr/local/lib/xorg/modules/input/joystick_drv.so
[    52.975] (**) Option "SendCoreEvents"
[    52.975] (**) Joy0: always reports core events
[    52.975] (II) No input driver specified, ignoring this device.
[    52.975] (II) This device may have been added with another device file.
[    52.975] (EE) PreInit returned 11 for "Joy0"
[    52.975] (II) UnloadModule: "joystick"
[    52.975] (II) Unloading joystick

    Can you help me, please, to understand what have I done wrong here?

    Thank you.
 
It seems like the gamepad buttons respond to:

uhidd -vvv -kmoh /dev/ugen1.3

Here is the result:

Now, I created a /usr/local/etc/uhidd.conf with this content, to map my gamepad buttons to keyboard buttons:

Code: 
# 0x045e is the vendor id and 0x009d is the product id.
# See `uhidd.conf(5)` manual page for details about configuration file.
0x045e:0x009d={
        cc_keymap={
		KEY_C="0x04"
		KEY_X="0x01"
		KEY_D="0x08"
		KEY_S="0x02"
		KEY_Z="0x10"
		KEY_V="0x20"
        }
}

Then restarted the uhidd daemon with:

/usr/local/etc/rc.d/uhidd stop /dev/ugen1.3

Nothing happens (I suppose after pressing gamepad buttons to see the C, X, D, S, Z and V key typed to the console). Another thing: how can I found the vendor id and the product id for my keyboard?
