When you say "Using just the latest code without your patches made suspend/resume work back into high speed mode (usb2)", does the USB3.0 HDD work fine in USB2.0 mode? (In this case the LED on the HDD will show green) If convenient, can your catch the dmesg with xhci debug flag on in both cases - with and without Sarah's patches? I can not open your last dmesg-patched.log. When I click the link, it only shows a webpage with the redhat logo :( Thanks, Andiry -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
