You might will get the docs for the ASIC, but this is already available.
You won't get anything else. You'll need to do the usbsnoop thing, scanning
under Windoze, log the usb traffic and decode the register settings.
The correct settings are part of the Windoze device driver and buried inside
the source code, which you won't get.
