All I want from kernel is allowing me to set whatever values I need for both usb_curlim and chg_curlim. (also when charging from an external battery pack it is very usefull too not to pump all its juice just to fill internal battery -> chg_curlim set to very low) > > btw your concept isn't working as you said yourself the USB current is > reset > to 500mA on powerdown.

Well, anyway, even if not perfect (chg_curlim following usb_curlim when it is changed), these settings proved really helpfull for me !
