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!). | |
