N900 had the PHY interrupt wired to the bq chip instead of twl4030, right? You can fix this issue similar to phy-twl4030-usb.c. In function twl4030_phy_power_on() we call schedule_delayed_work() that checks the state of the ID pin on boot up. I think that's only needed for the i2c based PHY's with MUSB, with the others the USB driver has a better idea of the current state.
