This means the quirks didn't apply. It's strange - I wonder if the usbhid module is built-in. What version of Ubuntu are you using ?

Dennis

@mitu Ubuntu 18.04.3 LTS, the latest.. clean install yesterday
do I need to run the terminal as admin?

mitu

Usually, if there's something needing admin rights - like loading/unloading module - it'e enough to add sudo before the command to run it as admin.

I don't have any more ideas what to check.
You can manually unload the driver (sudo rmmod usbhid), then load it with the quirks parameter set

sudo modprobe usbhid quirks=0x0314:0x0328:0x040

then check again if your encoder is detected as 2 gamepads.

you sire... are my new GOD!!... thank you so,so much... this DID the trick... it shows as 2 players AND no more spastic movement in menu! I need to get roms on there and see if all still works.. but i will let you know!

thanks a million times

mitu

.. this DID the trick ..

The command should be the equivalent of setting the module options (usbhid.quirks) with the .conf file, so I don't understand why it's not working via configuration, but it works from the command line (?).

Dennis

@mitu yeah it does, but does this mean i have to run it each time? Because that wouldn't be the best lol

Isn't the problem the line I added?
options usbhid quirks=0x0314:0x032..... etc
Because via the command line I did not use the 'options' text

The syntax is a bit different between the .conf file and the command line options, but the effect should be similar - I've tested it on an Ubuntu 18.04 installation, just like yours.

Can you double check if the options file is the correct path (file is in /etc/modprobe.d) and extension (.conf) ? If the options file is not correctly created, then the options won't apply automatically. If that's not the case, then you'll probably need to find a way to run the commands I posted earlier on each boot.

Dennis

@mitu yeah just checked and the file is 100% there.... it is read only btw and user is root... is that the problem.. i even tried adding another conf file without the rp- part.... i dont understand :(

Can't I add the line to another file and if yes, do you know how? Could it be the retropie install way I tried? See the url above which steps i used

No, the RetroPie installation doesn't affect the this part. Now that I'm thinking about it, there is another way - similar to how it's done for the PI: add the arguments to the boot loader (grub). See how it's done here - add the usbhid.quirks=0x16c0:0x05e1:0x040 fragment to GRUB_CMDLINE_LINUX_DEFAULT then run update-grub and reboot.

Dennis

@mitu this totally worked!!! thanks!!! b/c of new years eve and all I dont have time now to test a ROM and see if the controls work... on my friends Pi the controls worked in the menu but not in game... I will let you know!

thanks again so much and have a save and happy new year

Dennis

So, both controls are recognized! But now the controls do not work in game for player 1... in the menu I can use all the buttons but when starting a game only the right side of the arcade controls, so player 2 work.... nothing on the left arcade buttons work... also I couldnt exit out of the game for some reason... very weird.. any idea?

Dennis

Got of working via the retroarch mania thanks again for the amazing help

@dennis Thanks for asking, answers were really helpful to me.
I have the same Juyao Dual Arcade Joystick and I faced the same issue that you had.

My dual controller was recognized as one controller so I wasn't able to configure them separately.

My solution was this:

cd /opt/retropie/configs/all/retroarch-joypads
cp Xin-Mo Xin-Mo Dual Arcade.cfg D_R_M JUYAO Dual Arcade.cfg

then edited D_R_M JUYAO Dual Arcade.cfg
replacing vendor and product_id

the final file should look similar to this:

input_device = "D_R_M JUYAO Dual Arcade"
input_driver = "udev"
input_vendor_id = "0314"
input_product_id = "0328"

input_up_axis = "-1"
input_down_axis = "+1"
input_left_axis = "-0"
input_right_axis = "+0"

input_select_btn = "7"
input_start_btn = "12"

input_a_btn = "0"
input_b_btn = "3"
input_x_btn = "5"
input_y_btn = "2"
input_l_btn = "1"
input_r_btn = "4"

input_l2_btn = "9"
input_r2_btn = "8"

input_l_x_plus_axis = "+0"
input_l_x_minus_axis = "-0"
input_l_y_plus_axis = "+1"
input_l_y_minus_axis = "-1"

After doing that, I was able to configure them separately on retroarch.
