Hi,

first, thank you. Second, this is teaching me to question my
assumptions. There is no disconnect at all. We are busy looping
in the error handler as we have virtual hardware in this test,
which can execute an URB without waiting for hardware.

So should we kill error handling for this case?

	Regards
