+    This driver should provide support for most Aztech AZT2320 based cards.
+    Several AZT2316 chips are also supported/tested, but autoprobe doesn't
+    work: all module option have to be set.
+
+    No docs available for us at Aztech headquarters !!!   Unbelievable ...
+    No other help obtained.
+
+    Thanks to Rainer Wiesner <rainer.wiesner@01019freenet.de> for the WSS
+    activation method (full-duplex audio!).
