Solved Mapped 2P Buttons Don't Behave Correctly

[Substring]

@tdelios Hey Tom
I'll give you a lityle background info so that you get the trick Linux doesn't "naturally" understand devices such as the juyao or the xinmo the right way. Both are encoders that create 2 input devices on a single USB port. So to speak : that's a heresy for Linux. But, we can help Linux understanding how to set up the system for such devices with some "hacks" at the USB protocol level : this is called a (usb) quirk. There are several of them, and 0x40 means "set thz right bits so that linux shares a single usb devices as 2 input devices". I don't know how and where the share is made, but the kernel parameter you added means "for vendor id XXX and product id YYY, use magic number 0x40".

Concerning the mapping : this has been proven by the community to be working 100%, we have to rely on them as it never proved to be wrong. The doc must refer to windows which has a not so "usb protocol standard respectful" behaviour !

Hey guys.. just wanted to give you a great update. Flipping the 2P START and SELECT/COINS button did the trick.
Its so funny how there are so many image references on the internet saying the opposite and luckily the one link you provided showed the correct way.

not sure if the usbhid.quirks=0x16c0:0x5e1:0x040 being added to the cmdline.txt helped it or not, but I guess it doesn't hurt to keep it in there. Not sure if 4.1 will have this entry in there by default as a Nooby would pull their hair out trying to do it themselves.

anyhow, you guys have been great and I always anticipate the continued evolution of Recalbox !

cheers

As i explained above, the qurik is mandatory or you can't have 2 sticks from your xinmo, just one

@subs
anyway to for you guys to code Recalbox on your next version to detect the xin-mo and automatically add the quirk to the cmdline.txt?

I had spoken via email to a xin-mo manufacturer engineer and he said that he wasn't aware that different OSs have different interpretation on the pins as they are following the USB HID protocol. He said that I am probably using the XM-02 model that gave me the problem. He said that the XM-07 model may have better results to follow the pins as exactly as illustrated, and not to flip the START/SELECT as suggested by you guys. He forgot to mention how to tell them apart though .. lol...

In recalbox 4.1, xin-mo will be add.

@acris and @Substring ..

I found a link on the internet that outlines the 4.1 release items that the developers are still working on and the items that have been completed..

I do not see anything related to xin-mo and my problem.. Can you guys confirm that its on the list and that you guys are going to roll it out in 4.1 so that I don't have to manually go through the manual way of modifying the cmdline.txt file ..

cheers

@tdelios it has been already added to the 4.1 release, don't worry.
See:
https://github.com/recalbox/recalbox-buildroot/blob/master/board/recalbox/fsoverlay/etc/modprobe.d/usbhid.conf

[tdelios]

@paradadf thanks for the info buddy!

[tdelios]

@acris @Substring @paradadf

I thought you said that the 2P xin-mo fix was in the 4.1 release.

I am currently playing around with the 4.1 latest version and the button mapping is just as bad as before.
My 1P SELECT button is acting like the 1P Start and vise versa and my designated "A" button has become the Hotkey button.
I double checked the wiring and it is fine..

any thoughts on how to trouble shoot this?

[Substring]

@tdelios which board are you using ?

[tdelios]

@Substring How can I tell? I was just told that it was a 2P xin-mo and by looking at it, it has 18 pins for each player

[Substring]

@tdelios I meant pi ? odroid ? x86 ?

[tdelios]

@Substring Raspberry Pi3

[Substring]

@tdelios For the xin-mo, you should only map the first player and force it as player 1, the system will autoconfigure the P2 (both inputs and player position)

[tdelios]

@Substring what do I set the 1Player and 2Player values on the controller setup.

1Player = "#0 Xin-Mo" and 2Player = "Default"

or

1Player = "#0 Xin-Mo" and 2Player = "#1 Xin-Mo"

[tdelios]

@tdelios nvm.. read the previous post history on this

[tdelios]

@Substring your awesome!

it was my mistaken to configure the buttons for both controllers.. .Once I configured only the 1 PLAYER and not both.. and then setup the controller for 1P = #0 XIN-MO and 2P = #1 XIN-MO .. then I was good to go..

THANKS!
tom

@tdelios i'm glad you can now enjoy your recalbox

[subvers]

@Substring maybe you can help me.
I have a 3H Dual arcade encoder(it's a xin-mo clone) and managed to configure player 1 and 2 but the problem is that I cannot use diagonals on the joysticks, for example down-right. I use rasberry pi with the last version of recalbox.

[Substring]

@subvers no hadoken possible ? Which version number is your last recalbox ? 4.0.2 or 4.1 ?
