Can you share your code, and take glitch traces?

[solved?]
A degree of success with USB devices on Windows 7.
I have got the renderer to work correctly by *not* calling
IAudioClient::GetCurrentPadding() when in exclusive mode. It simply results in
glitches.
Does this make any sense? The docs do not imply this is a bad idea ...

Even with this fix, the M-Audio PCI card is still glitching badly and the
on-board HDA produces nothing at all.
we've a total buffer size of 441 * 2 * 16? with data interleaved as
[L0][R0][L1][R1][...][Ln][Rn]
Where n == 441 of course.
