There should be no need for that.
twl4030-usb is using ulpi interface on 3430sdp, which means all interrupts
are
directed to musb using that interface, also musb switches between
host/peripheral
roles automatically as long as we get an id pin change interrupt.

Somehow this interrupt is not going to musb's driver when we're using ulpi
on 3430.

I have some other questions for you but it'll be privatly.
