If you applied the patch, I guess you may see __twl4030_phy_power(twl, 0) is called from .probe. If called, seems your description a little contradictory since you observed __twl4030_phy_power(twl, 0) may hit proper values, right? If not called, could you trace the return value of twl4030_usb_linkstat in twl4030_usb_phy_init? thanks, -- Lei Ming -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
