Our hardware team reports that there are some failures seen without the a custom PHY driver. Do you require this PHY driver on regular operation on Stingray? Or is this for some specific functionality? I am asking since the issue reported here is on switching between a USB 3.0 and USB 2.0 devices. Any plans on submitting this driver again? Thanks, JC
