Can we explain what the problem was? D457 MIPI devices were recognized before even without all the work done on backend_device_group etc. - so what kept us from recognizing D457 MIPI recovery devices?

As discussed let's also notify the user that if the device is D457 and we are recovering form a recovery mode, after the process finish it will not finish with a timeout message he will ask the user to reload the D4xx driver or reboot the platforn
