I'm assuming that you are using a lower filter? You might want to use a GFX (Global Effects?) filter instead? I don't remember if that works on Me - it's supposed to work with XP / USB Audio. Thanks.

The concept works fine in Windows 98 and Windows 2K, XP with out any problem . In case of windows Me , when the Transfer buffer of URB request contains Zeros always . If I don't touch the data buffer in URB then I can see some data coming out of Iso pipe . Did anybody see the similar problem . And I don't see any problem when I am sending the data up through Iso IN pipe. The problem occurs only on Iso OUT pipe . Are there any restrictions on sending data on Iso OUT pipe in Windows ME ? Any ideas how to solve this problem ? Thanks in advance. Sri. __________________________________________________ Do you Yahoo!? Yahoo!
