9 This driver should provide support for most Aztech AZT2320 based cards.
10 Several AZT2316 chips are also supported/tested, but autoprobe doesn't
11 work: all module option have to be set.
12
13 No docs available for us at Aztech headquarters !!! Unbelievable ...
14 No other help obtained.

16 Thanks to Rainer Wiesner <rainer.wiesner@01019freenet.de> for the WSS
17 activation method (full-duplex audio!).
