-    # --- Rules for WebHID/WebUSB Permissions for Keychron Devices ---
-    # These rules aim to make ALL Keychron devices accessible to users in the 'plugdev' group,
-    # or the 'users' group, so browsers (running as that user) can potentially interact.
-
-    # This rule targets any Keychron device by its Vendor ID.
-    # It sets the group to 'plugdev' (or 'users') and grants read/write permissions.
-    #
-    # Considerations:
-    # 1. 'SUBSYSTEMS=="usb"': Matches devices within the USB subsystem, broad enough for WebUSB/WebHID.
-    # 2. 'ATTRS{idVendor}=="3434"': Specifically targets Keychron devices.
-    # 3. 'MODE="0660"': Grants read/write to owner (root) and group (plugdev/users).
-    # 4. 'GROUP="plugdev"': Assigns the 'plugdev' group. You might use 'users' or 'your-username-group'
-    #    if 'plugdev' isn't suitable or doesn't exist on your system.
-    #    The group used here must be one that your *browser's user process* is a member of.
-    #
-    # IMPORTANT: Do NOT use this rule for your primary system keyboard/mouse
-    # if you want to prevent web pages from *potentially* messing with them.
-    # For a general-purpose keyboard, the OS typically blacklists it from WebHID.
-    # This rule is most useful for custom peripherals or secondary devices.
