Hi,

 

We are using imx28 board.

lltib package is 130130.

Driver : USB

 

Our doubt is how to monitor over-current on usb port.

So that we have to disable power enable pin of usb once over-current is detected.

 

Please let us know what all changes have to be made in kernel in order to monitor usb overcurrent & disable power to usb once it gets overcurrent.

 

Please reply ASAP

 

Thanks in advance
