Philip,
Bizarre problem. I’m afraid that I’m out of ideas. It is always
difficult to debug stuff on a customers machine when the problem can’t
be reproduced. I agree that the fact that it only turns up at 96k
would seem to indicate that the machine, itself, is not at fault.
When the problem occurs do you have to reboot to get back to proper
operation or do you reattach your device or can you simply restart the
user application?
