Hi,

In our application, we are using over-current detection to control Vbus supply using Vbus enable pin.

But after detection of USB over-current signal, processer assert a low signal to Vbus enable pin and remains low though USB device is removed from the device, we require to reboot the device to work USB again.

Regards,
