21 This driver should provide support for most Aztech AZT2320 based cards.
22 Several AZT2316 chips are also supported/tested, but autoprobe doesn't
23 work: all module option have to be set.
24
25 No docs available for us at Aztech headquarters !!! Unbelievable ...
26 No other help obtained.
27
28 Thanks to Rainer Wiesner <rainer.wiesner@01019freenet.de> for the WSS
29 activation method (full-duplex audio!).
