One controller connected, ES says there are two

calcu10n

Hi folks,

I am using an SN30 Pro wired controller. When I initially tried to set it up, I noticed the trigger buttons weren't working. After updating the firmware, trying again, and poking around some more I found a thread where someone described the same issue. The solution was to install xboxdrv. I did so and this solve the problem and the controller has been working great since.

However, since installing xboxdrv I have noticed that ES thinks there are two controllers connected when there is only one connected. Doing some searching on the forums, I came across this:

https://retropie.org.uk/forum/topic/17650/dualshock-controllers-on-4-4-with-3b/22

Running cat /proc/bus/input/devices

I can see the same controller showing up twice:

I: Bus=0000 Vendor=0000 Product=0000 Version=0000
N: Name="Xbox Gamepad (userspace driver)"
P: Phys=
S: Sysfs=/devices/virtual/input/input1
U: Uniq=
H: Handlers=event1 js1
B: PROP=0
B: EV=b
B: KEY=7fdb0000 0 0 0 0 0 0 0 0 0
B: ABS=3001b

I: Bus=0000 Vendor=0000 Product=0000 Version=0000
N: Name="Xbox Gamepad (userspace driver) #2"
P: Phys=
S: Sysfs=/devices/virtual/input/input2
U: Uniq=
H: Handlers=event2 js2
B: PROP=0
B: EV=b
B: KEY=7fdb0000 0 0 0 0 0 0 0 0 0
B: ABS=3001b

So it looks like creating a udev rule may solve it? I've never done that before, so I'm not exactly sure where to start. I could also be completely wrong. Any guidance would be appreciated!

xboxdrv install method: Installed from source
Emulationstation Version: 2.9.6RP
Built From: Pre made SD image on RetroPie website
RetroPie Version Used: 4.7.1
RetroPie Image Filename: retropie-buster-4.7.1-rpi4_400.img.gz
Installed Hardware: Raspberry Pi 4 8GB, SN30 Pro USB controller, USB extension cable (I've tried with and without the extension cable, issue is the same)
How to replicate: Not entirely sure

Thanks in advance!

Update your RetroPie-Setup script to the latest version, remove the xboxdrv 'driver' (which is not really a driver), then re-install the xpad driver. Re-configure the gamepad in EmulationStation and the triggers should be recognized.

Ok, I've just done that, but ES still sees two controllers when there is only one connected. Any suggestions? (I also restarted ES just to be sure)

The 2nd controller appears because of xboxdrv - make sure it's uninstalled.

I just verified again, it is uninstalled. I have rebooted the host and that sorted it out. thank you!

Hmm... well I sort of spoke too soon. Now the controller isn't working right. After rebooting I have re-mapped the controls again, but the buttons aren't functioning correctly. As an example: it's taking the trigger as the start button, even though I mapped the buttons correctly. I remapped again and it's still the same. Suggestions?

hmm. just reinstalled xpad from source again, remapped and it seems to be working now. all good. thanks again!
