Hi,

1, Does Microsoft release USB2.0 audio driver for
Win2000?

I know Microsoft supports USB2.0 audio driver in Win
XP SP2.but I have no idea about Win 2000. Does
Microsoft support USB2.0 audio driver in Win2000 SP4?


2,How to write own USB2.0 audio driver for Win2000?

If Microsoft does not, I have to write our own USB 2.0
driver for Win2K. Since our device (Audio & Video)
needs to support both XT and Win2K. Microsoft DDK only
give some PCI audio WDM driver source code.
It is still difficult to modify it to USB audio WDM
driver.

Can someone kindly let me know where I can get USB
audio WDM driver sample code?


Thanks very much

Jeff
