+# /* When token is hot-unplugged:
+#  * - in Linux (pcsc-lite)
+#  * -- SCardGetStatusChange returns OK;
+#  * -- current reader state is 'UNKNOWN';
+#  * -- 'Refresh-attributes' returns 'SC_ERROR_READER_DETACHED'.
+#  *
+#  * - in Windows (WinSCard):
+#  * -- SCardGetStatusChange failes with SCARD_E_NO_READERS_AVAILABLE;
+#  * -- 'Refresh-attributes' returns 'SC_ERROR_NO_READERS_FOUND'.
