I actually did:
if (hcd->state == HC_STATE_SUSPENDED)
usb_hcd_resume_root_hub(hcd);
else
usb_hcd_poll_rh_status(hcd);
Anyways I noticed something weird when testing remote wakeup. I
plugged a mouse and then suspend it through sysfs:
$ echo -n 3 > /sys/bus/usb/devices/.../power/state
$ cat /sys/bus/usb/devices/.../power/state
3
mouse is suspended. I push on one of its buttons to remote wakeup the
device. The device is woken up but if I look at the state in sysfs,
it's still suspended:
$ cat /sys/bus/usb/devices/.../power/state
3
Am I missing something ?
Thanks
