This is an important point which I did not see or answer, due to some confusion locally. I'm sorry. Yes, we wait for the reset between setting the reset state (port feature), and clearing it, thus enabling the device for normal operations. However, there is no delay of any sort after clear_port_feature() call. In no way changing parameters alters this situation. > > What is up with that? Does Windows do it?
