+  # This patch addresses a bug discovered in the HidApi IOHidManager back-end
+  # that is being used with Macs.
+  # The bug was dramatically changing the behaviour of the function
+  # "hid_get_feature_report". As a consequence, many applications working
+  # with HidApi were not behaving correctly on OSX.
