Hi, Currently I'm facing a problem on USB remote wakeup from hibernation. When plug a USB1.1 keyboard to EHCI/OHCI port, press button during suspend and hibernation can wakeup the system; However, when I plug the keyboard to xHCI port, press button can only wakeup the system from suspend, but not from hibernation. I think the driver should treat the USB keyboard remote wakeup the same way for both suspend and hibernation(set remote wakeup request to the device, suspend it and the host, etc). I don't know why remote wakeup for suspend and hibernation behaves differently on xHCI port. Any suggestions? Another question is I can see usb_port_suspend() and xhci_pci_suspend() getting called during suspend, but I cannot see them called during hibernation, either by adding print message and using ftrace. Are they not called at all during hibernation, or just print message and ftrace fails to catch it? Thanks.
