multiple controllers

[Mernst1]

when using multiple controller for example 2. In Steam Big Picture Mode there is always an input what it makes nearly impossible to navigate in there, also in games I notice this problem that there is unwanted input. I think always games where you can control the main menu with all four controllers not only with the first.

When I make the config file only with one controller everything works as expected. My config file:

[ds4drv] daemon=false hidraw=false

[controller:1] led=0000ff emulate-xpad=true battery-flash=true trackpad-mouse=true

[controller:2] led=ff0000 emulate-xpad=true battery-flash=true trackpad-mouse=true

[controller:3] led=00ff00 emulate-xpad=true battery-flash=true trackpad-mouse=true

[controller:4] led=ffff00 emulate-xpad=true battery-flash=true trackpad-mouse=true

[bindings] PS+Triangle = exec-background killall -KILL pcsxr PCSX2 mupen64plus dolphin-emu snes9x-gtk reicast PPSSPPSDL

Edit: found out that the default axis values for the non used controllers, that were created by the config file are wrong. This explains the strange behavior in steam and some games.

I'm having this issue as well. Axes 0-6 all have a default minimum value of -32767 which is causing spurious input. This will happen with even a single controller if it has not yet been connected. I've tried to modify the code myself but unfortunately python is not a language that I am comfortable in, and all attempts were for naught.

One thing I have noticed, though, is that these values all get set to 0 when a controller disconnects.

Current workaround is to connect the amount of devices that I'm going to use, but that means manually inputting commands rather than have a script running automatically at boot. This tool would be infinitely better if this problem was solved.

Would like to add an update.

Adding the following line to the constructor of UInputDevice in uinput.py fixes the issue:

self.emit_reset()

Of note, it does not change the output of the joystick or jstest tool, but it does get rid of the spurious input that occurs in Steam and other applications.

I suggest anyone that has this problem try this and reinstall ds4drv.

It doesn't seem like the original developer is active anymore. Pull requests are being ignored, and the last commit was 2 years ago.

There are available lot of useful patches now, but nobody merging them in. Maybe it's best if someone can maintain a fork, and accept the patches there. At least until/if the original developer comes back.

I merged the fix.

fix doesn't work on new version 0.5.1. Problem is the same like in 0.5.0. cant find out why, when I apply the patch on 0.5.0 uinput.py its working.

@Mernst1 Could you test if #75 with latest master fixes the issue for you?

[Mernst1]

@Ape Yes!!! the new fix makes it running again. Great work! thank you @Ryochan7. Can be closed.
