Corsair K65 Wireless Receiver detected also as Joystick

Hey all, curious thing - This receiver is also detected as a gamepad in KDE Gamepad settings and Steam actually tries to also use it as a gamepad:

N: Name="Corsair K65 PLUS Wireless Receiver Keyboard"
P: Phys=usb-0000:14:00.0-1.4/input0
S: Sysfs=/devices/pci0000:00/0000:00:08.3/0000:14:00.0/usb9/9-1/9-1.4/9-1.4:1.0/0003:1B1C:2B07.0007/input/input9
U: Uniq=71FC8113F1110D5E
H: Handlers=sysrq kbd leds event9
B: PROP=0

N: Name="Corsair K65 PLUS Wireless Receiver Mouse"
P: Phys=usb-0000:14:00.0-1.4/input0
S: Sysfs=/devices/pci0000:00/0000:00:08.3/0000:14:00.0/usb9/9-1/9-1.4/9-1.4:1.0/0003:1B1C:2B07.0007/input/input10
U: Uniq=71FC8113F1110D5E
H: Handlers=event11 mouse2
B: PROP=0
--
N: Name="Corsair K65 PLUS Wireless Receiver"
P: Phys=usb-0000:14:00.0-1.4/input0
S: Sysfs=/devices/pci0000:00/0000:00:08.3/0000:14:00.0/usb9/9-1/9-1.4/9-1.4:1.0/0003:1B1C:2B07.0007/input/input11
U: Uniq=71FC8113F1110D5E
H: Handlers=kbd event12 js0
B: PROP=0

see js0 at the last entry? Is this expected behaviour? I had to manually add udev rules:

SUBSYSTEM=="input", ATTRS{name}=="Corsair K65 PLUS Wireless Receiver", ENV{ID_INPUT_JOYSTICK}="0"

To prevent it being detected by apps - however the device js0 still exists:

/dev/input/js0 - so I'm not sure if this will cause issues in the future. On the other hand - i had a lot of problems with the wireless mode where the keyboard randomly lost connection with the wireless adapter and I think it might have been caused with some conflicts with this js0 device (For example I had games spinning camera out of control in Steam so I guess it must have been mapped as a pad and cause some issue) where now I've been using this machine for a day with the udev rules and it doesn't happen.

Kernel:

6.15.8-zen1-1-zen #1 ZEN SMP PREEMPT_DYNAMIC Thu, 24 Jul 2025 18:17:55 +0000 x86_64 GNU/Linux

Has anyone else had this problem maybe? I'd like to figure this out

Has it always been this way?

Re: Corsair K65 Wireless Receiver detected also as Joystick

Well I haven’t been using Linux on this machine for long, but it’s been like this since about 2 months, ever since I installed it
Edit, I also made rules that actually remove the /dev/input/js0 device, however some games STILL detect it as a controller

SUBSYSTEM=="input", ATTRS{idVendor}=="1b1c", ATTRS{idProduct}=="2b07", ENV{ID_INPUT_JOYSTICK}=="?*", ENV{ID_INPUT_JOYSTICK}=""
SUBSYSTEM=="input", ATTRS{idVendor}=="1b1c", ATTRS{idProduct}=="2b07", KERNEL=="js[0-9]*", RUN+="/bin/rm %E{DEVNAME}", ENV{ID_INPUT_JOYSTICK}=""

after reload:

ls /dev/input/js*
zsh: no matches found: /dev/input/js*

1.7214s INFO| Initializing console...
