+ 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!).
