USB autosuspend suspends vhci_hcd. In this process hcd_bus_suspend gets executed which puts vhci_hcd in suspend state and calls vhci_hub_status. vhci_hub_status function checks hub state and if it is in suspend state, usb_hcd_resume_root_hub gets executed which resumes hub and if hub is idle, again autosuspend puts it in suspend state and this goes on. vhci_hub_status should resume hub only when hub port is in suspend state and hub port status has changed.
