i want ask , my USB First insert / detected is slow , then after i plug out and pluggin again , the usb is fast detected ... it's normal like this ? or have something problem with my driver or OS?
This may help to speed it up. I can't be certain it's the wall you are hitting though.
To Disable Selective Suspend:
open the control panel
go to power options (you may have to set view to small icons)
click change plan settings
in the window that opens:
click change plan settings
click change advanced power settings, expand usb and ensure usb selective suspend is disabled.
I'm fairly sure the source of your slow initial is a power setting. I'm just not 100% on which one it would be in this instance.
