Oh, I must have missed that information. Sorry about that.
So, the situation is that if you set up the USB3 controllers to wake up
and next you wake up the system from S3 using a USB device connected to one
of those controllers, then they appear to be in D3 after the resume and
apparently cannot be put into D0. However, if the wakeup is done in any
different way, they work correctly after the resume, right?
Is that the case on both the affected systems?
