# OpenLogi udev rules
#
# Grants the active-seat user read/write access to Logitech HID devices and the
# uinput kernel module — no group membership required on systems running
# systemd-logind (uaccess tag).
#
# Install:
# sudo cp 70-openlogi.rules /etc/udev/rules.d/
# sudo udevadm control --reload-rules
# sudo udevadm trigger
#
# Non-systemd fallback (SysV init, OpenRC, etc.):
# Replace TAG+="uaccess" with MODE="0660", GROUP="input" and add your user to
# the 'input' group: sudo usermod -aG input $USER (re-login required).
# Logitech HID++ receivers and directly-connected devices (hidraw interface).
# Two rules are needed to cover both transports:
# - USB / Unifying / Bolt receivers: ATTRS{idVendor} walks the USB sysfs chain.
# - Bluetooth (uhid virtual bus): ATTRS{idVendor} is absent; match on the HID
# kernel name format "bus:VID:PID.iface" whose VID field is always uppercase.

# uinput virtual device node — needed for the evdev/uinput input hook.
# OPTIONS+="static_node=uinput" creates the node at boot even before any device
# is plugged in, so the agent can open it without a trigger.
