USB susped/resume

Hi All,

Could you please clarify below query related to USB auto suspend nad resume.

If we initiate resume immediatly after auto suspend, how hub driver will handle the port connected to the device.

I guess it all depends on how resume works in your distro and with your hardware. If resume is configured to reinitialize the port or if suspend doesn't shut it down, than your set. Then again, that's providing that your hardware allows it.
If you are looking for a more technical answer, you'll have to be patient and wait until someone who knows the inner working of suspend and resume comes along to explain it in more detail.
