# ls /dev/ | grep usb

usb
usbctl

Where is my /dev/uhidX ?

Same for me, I have none.

 

[USerID]

I see. Thank you. As Lenin said, we will take a different path.

do you have a hcons in dmesg ?
like
hcons0: <Apple Inc. Apple Keyboard Consumer Control> on hidbus1

 

[USerID]

$ dmesg | grep hcons

hcons0: <Telink Wireless Receiver Consumer Control> on hidbus0
hcons1: <HS6209 A4tech 2.4G Wireless Device Consumer Control> on hidbus1

 

[covacat]

hcons devs should add some /dev/input/event* nodes which in theory are usable in X (evdev)
my kbd creates data in /dev/input/event4 and event5 or something when pressing multimedia keys

 

[USerID]

/dev/input $ ls -lah

Is it so surprising that instructions from 2011 may not work in 2025?
Maybe search for something newer based on usbhid?
I am sure I've seen materials on this site.
