Mmm, if I remember correctly my flatmate's Lenovo T400s has a powered USB port which works both when the laptop is suspended as well as when it's turned off... we were hoping to have USB powered during suspend on 1.5, but were foiled by poor documentation of the gpio pins in question. Okay, too bad to hear that. Will you make another attempt for the XO-1.75?
