A peculiarity I noted on my X201 is that it does not seem to have any USB 1.x controllers, only ehci 2.0, yet the man page says that "EHCI controllers are peculiar in that they can only handle the USB 2.0 protocol". I wonder if these boxes have some strange ohci or uhci controllers that are not detected, or some kind of integrated 2.0/1.x controllers that the ehci driver does not fully understand and therefore is causing the resume issue? (Yes, I also have the USB resume issue after a couple of resumes.) Bengt > Unless there really is some cross-relatedness, I'm very keen to see the > two issues disentangled.
