just a short update, also a bit of a reminder for myself

according to my recent studies, "twl4030_usb_irq" is the first interrupt executed after applying VBUS and sometimes (?) also after plugging in a selfpowered hub.

this interrupt checks the state of the ID pin by calling "twl4030_usb_linkstat". Therefor I tried to fake the state of the ID pin in this function. I was in a_idle after that, and interrupts occured after plugging in peripherals. But I couldn't get my n900 to enumerate them.

Too tired to continue now, but perhaps somebody finds this information useful
