Hello,
a couple of months ago I was programming a driver for an audio USB 2.0
Interface. My first attempt was to try to get the device running with an
audio test program written in user space, so i could debug my code easier
( using the USB user space Interface ). I gave up on the attempt because
my interrupt streams would constantly crash, when to much data was
transfered on an Isochronus Pipe. I wrote the problem to this usb-list and
i was told that this was a known bug in Mac OS X.
Months later, i tested the user space program again ( after updating to
10.3.9 ) and to my surprise the test program worked perfectly, without
changing any code!! I then checked the ChangeLogs of Mac OS X but i didn't
find any clue that something was changed in the USB implementation.
It wouldn't really interest me, if the same problems that i had in the
user space program weren't occuring in the kext version of my driver now.
So my question: what exactly did change? Did it also change in the kernel?
