Hi Dave,
I can reproduce the error with a Creative CPiA
on a K6 II+(500Mhz)/SIS5598/linux-2.4.5ac7.
And I have also found a bug but it seems it's not the 'right' one
for this problem:
urb_free_priv () just unmaps the last part (belonging to the last TD)
of the data buffer.
So I will keep on searching :)
