I've previously found OpenRGB's udev rules to be a really good example since there's a bit of everything in there: https://openrgb.org/releases/release_0.9/60-openrgb.rules
But I think you'd want something like: SUBSYSTEMS=="usb|hidraw", ATTRS{idVendor}=="REPLACE WITH USB VENDOR", ATTRS{idProduct}=="REPLACE WITH USB PRODUCT", TAG+="uaccess"

Misunderstanding aside, thanks for the link!
