regra udev não funciona em Raspberry Pi 3

1

Estou tentando separar alguns teclados para que eles não sejam lidos pelo Qt em um Raspberry Pi. Estou usando uma regra udev para fazer isso, mas não parece estar funcionando. Estou tentando direcionar /dev/input/event3 para /dev/input/ccreader e /dev/input/event4 para /dev/input/barcode . Alguém poderá me indicar a direção correta? Vou postar todas as informações abaixo:

# udevadm info --attribute-walk --name /dev/input/event4
Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

Se parecer que sua regra está sendo ignorada, você pode tentar uma recarga completa. udevadm control --reload nem sempre funciona (obrigado systemd).

systemctl force-reload udev systemd-udevd-control.socket systemd-udevd-kernel.socket
