So i dont have any idea where can i call pm_runtime_put for my usb device? the other thing is that, earlier you have told, waking up usb device through interrupt is same as writing "on" to ../power/control , but i think writing "on" to ../power/control will disable the autosuspend for usb device in future, but i want autosuspend to be enabled for my usb device always. Will using pm_runtime_get and pm_runtime_put cause the disable of autosuspend for usb device?
