Trap 00d in usbaudio.sys bldlevel 10.70 kernel 14.104a_uni

[Rainer Stroebel]

I am testing the usbaudio .sys driver to use with usbs audio adapters
form Emkey and Creative Labs.

The Adapters has mic In and speaker out function.

The adapters works with good sound input and output quality in with
window 2000 standard usb sound drivers with application speech
recognition Via Voice.

Just to document the hardware is okay!

usbbase drivers are at current level.

Problem 1: The sound quality is pure with all tested bldlevels of
usbaudio.sys

Problem 2: The latest bldlevel 10.70 a viable to me even Traps!

bldlevel 10.69 does not trap, but produces bad sound
quality like all previous builts.


Here are the Trap info

Additional info: the trap accured at boot / loading /init driver.
