+# chwd has a sequential search for the desired profile. First it goes through

+# the profile specifies which manufacturer's driver we need via vendor_id,
+# after which chwd select specific device in device_id or device_pattern, which
+# is how much wider and includes devices of the same generation. For example:
+#
+# Searched for 3D controllers
+# class_ids = "0302"

+# Filters only NVIDIA GPUs
+# vendor_ids = "10de"

+# A certain device or set of ids:
