Thanks Clemens, We have to build our own because we do a lot of custom stuff in our driver specific to our products. We've considered purchasing a driver from various companies, but for several reasons, we have decided to spin our own, so my question is assuming we need to build our own. Just interested in opinions between the various approaches. -Dan -----Original Message----- From: wdmaudiodev-bounce@xxxxxxxxxxxxx [mailto:wdmaudiodev-bounce@xxxxxxxxxxxxx] On Behalf Of Clemens Ladisch Sent: Friday, November 12, 2010 1:35 AM To: wdmaudiodev@xxxxxxxxxxxxx Subject: [wdmaudiodev] Re: KMDF and AVStream revisited Daniel Rice wrote: > My company is currently building a new windows usb audio driver ... > I'm interested on opinions as well as alternate approaches to what we have > listed. An alternate approach would be to make the device's firmware compatible with the USB Audio Class so that you can use the OS driver. If you need features of Audio Class v2.0, your device would be supported by OS X and Linux; for Windows support, you'd have to wait until Microsoft bothers to write the driver, or buy it from Thesycon.
