The issue is documented in the file itself: eroen@occam ~ $ head /lib/udev/rules.d/42-logitech-unify-ltunify.rules # Allows non-root users to have raw access the Logitech Unifying USB Receiver # device. For development purposes, allowing users to write to the receiver is # potentially dangerous (e.g. perform firmware updates). # skip actual unified devices, only consider the receiver DRIVERS=="logitech-djdevice", GOTO="not_unify_recv" # official Unifying receivers SUBSYSTEM=="hidraw", ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c52b", GOTO="unify_dev" SUBSYSTEM=="hidraw", ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c532", GOTO="unify_dev" Alternatively, the TAG and MODE lines could be commented out, the file could be hidden behind a USE flag, the file could be installed alongside documentation for easy symlinking into /etc/udev/rules.d, or an empty file could be installed as /etc/udev/rules.d/42-logitech-unify-ltunify.rules to mask the rule by default. For context; a user would generally only need write access to the receiver once for pairing after new hardware is added to a system.
