To allow users to use all features add them to the 'roccat' group To allow udev to detect your device without reboot, run # udevadm control --reload-rules && udevadm trigger --subsystem-match=usb ************************* *** Upstream message: *** ************************* * Some devices (Arvo, Kone) need uinput for some features. To use it as normal * user you can either create an extra group like uinput-users and add yourself * to this group (as described above) or reuse group roccat. * Create a file like /etc/udev/rules.d/90-uinput.rules containing the line * KERNEL=="uinput", GROUP="uinput-users", MODE="0660" * and replace the group name with your choice. * In addition, you need to enable CONFIG_INPUT_UINPUT in your kernel * Do a logout/login to apply your new group ownership and replug your device * and everything should work as expected.
