This is actually v4.
With this patch applied, dmesg on device plug looks like this and has no more
suspend-resume-cycle:
[ 454.845205] xhci_hcd:handle_port_status: xhci_hcd :00:14.0: Port Status
Change Event for port 19
[ 454.845215] xhci_hcd:handle_port_status: xhci_hcd :00:14.0: res
x27;t yet available.
If a warm-reset request is detected, this sets the hubs event_bits,
which will prevent any auto-suspend and allows the hubs workqueue
to warm-reset the port later in port_event.

Hi,
just wanted to know if the logs are usable and if you now need some additional
information.
Now I should also build usbcore as a module, so I don't have to reboot all the
time. And I'll try to look into the code to understand the port status value.
AFAIK the log suggest that for whatever r
