When a process without full /dev/input access enumerates devices via libudev-devd,
|
|
the udev_device structs do not get udev properties that mark them as inputs, keyboards, etc,
|
|
and get rejected as not being input devices.
|
|
|
|
libinput reopens devices just to check path equality.
|
|
The udev_devices from reopening do have the right properties,
|
|
so we just use them instead of the original (enumerated) ones.
