Making *all* devices from these two vendors world-writable is too dangerous, this can't go into a default distro rule. This needs to be restricted to either particular product IDs/patterns, or better yet, to particular device classes. What are these anyway, something like joysticks or game controllers? Does input_id recognize them as anything in particular, ideally ID_INPUT_JOYSTICK=1?
The comments should also explain more than just "USB devices" Please do "udevadm info --export-db > /tmp/udev.txt" and attach the file here; I'd like to see what we already know about these devices. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1498655 Title: Steam Controller support: need read-write access to Valve-owned input event device nodes. Status in steam package in Ubuntu: Confirmed Status in systemd package in Ubuntu: Incomplete Bug description: The Steam Controller is about to roll out; for the Steam Controller to be supported properly by the Steam Client, it needs to be able to read and write to HID device nodes that have the Valve USB vendor ID. In our own Steam package 'steam-launcher' [1], this is achieved by a udev rule [2] matching our vendor ID. There doesn't seem to be such a udev rule in the Ubuntu-provided package, meaning Ubuntu users will not be able to use the Steam Controller out of the box.
