In order for two devices to be in the same group, they need to share identical LIBINPUT_DEVICE_GROUP attributes. The `wacom_handle_ekr` function overwrites the VID/PID for an ExpressKey Remote, but the 'phys' path is left unchanged. This only works if the EKR and the device we want to pair it with are both direct sibings in the USB tree. It isn't always possible to actually connect the devices like this, however. The Cintiq Pro 32 and 24, for instance, have multiple internal USB hubs and place the pen sensor and the USB port for the EKR dongle behind different ones. By copying the 'phys' path of the device we want to pair with, it is possible to reproduce the entire LIBINPUT_DEVICE_GROUP and ensure that the two devices actually end up paired in libinput.

libinput
libinput is a library that provides a full input stack for display servers and other applications that need to handle input devices provided by the kernel.
libinput provides device detection, event handling and abstraction to minimize the amount of custom input code the user of libinput needs to provide the common set of functionality that users expect. Input event processing includes scaling touch coordinates, generating relative pointer events from touchpads, pointer acceleration, etc.
User documentation
