Thanks for the heads up. We're aware of that kind of issues, of
course, but this is not the kind of problem we're hunting here. The
driver/hardware/cable combination is proven to work in many different
setups, but fails with newer machines. We're currently digging for the
root cause of this, but all we got is still only some suspects, no
evidence yet. It seems to be limited to newer MacBookPros with 4GB of
RAM, and it does happen with other hardware and totally different driver
stacks (ie, FireWire sound cards).
We'll get back to you once we found more things to hold on.
Thanks,
Daniel
