ADDITIONAL INFORMATION
after some investigations I noted that m_uid variable in device.c not populated
and consequently my cam is ignored by isValid() method, if I populate m_uid
variable with any value the cam is not ignored and it works well.
I noted also that "gst-device-monitor-1.0 Video/Source" output return
udev-probed = false
Inside gstreamer sources
(https://gitlab.freedesktop.org/gstreamer/gst-plugins-good/-/blob/master/sys/v4l2/
gstv4l2deviceprovider.c) you can see that sysfs.path is set only for udev
probed device (row 249) but not in other case (row 122+)
