Developed for but can work with others, it should but there is no garantee
2+
Playstation DualShock4 controller hw_version=0x0000b418 fw_version=0x0000a00b
3+
4+
I could not get Dpad to work with this API but the Sticks works.
5+
I use the Dpad only around edges but can play without it.
6+
This is just a way to take the kernel RAW when everything else is not working
7+
You might just need to replace this line.
8+
device = evdev.InputDevice('/dev/input/event21') # Replace X with the correct number
9+
10+
The quick way:
11+
sudo modprobe uinput
12+
sudo chown root:input /dev/uinput
13+
sudo chmod 0660 /dev/uinput
14+
15+
Fixing /dev/uinput Permissions
16+
17+
To make it persist across reboots, add it to /etc/modules-load.d/uinput.conf:
18+
19+
echo "uinput" | sudo tee /etc/modules-load.d/uinput.conf
20+
21+
2 Give Your User Access to /dev/uinput
22+
23+
By default, only root and the input group can access it.
24+
25+
Add yourself to the input group:
26+
27+
sudo usermod -aG input $USER
28+
29+
Log out and back in (or reboot) for the group change to take effect.
30+
31+
If that still doesn't work, you might need udev rules.
32+
3 Create a udev Rule to Fix Permissions
33+
34+
If /dev/uinput still has crw------- (only root access), create a new rule:
35+
36+
sudo nano /etc/udev/rules.d/99-uinput.rules
37+
38+
Add this line:
39+
40+
KERNEL=="uinput", GROUP="input", MODE="0660", OPTIONS+="static_node=uinput"
41+
42+
Then apply the new rule:
43+
44+
sudo udevadm control --reload-rules && sudo udevadm trigger
45+
46+
Now, check if the permissions are fixed:
47+
48+
ls -l /dev/uinput
49+
50+
It should look like:
51+
52+
crw-rw---- 1 root input 10, 223 Feb 1 4:20 /dev/uinput
53+
54+
If it still says crw-------, reboot.
55+
56+
Now your Python script should be able to read/write to /dev/uinput without sudo! 🚀
