Re: USB charging while XOs are switched off

Is this a feature that has been considered for the XO-1.75? Laptops don't typically provide power over USB when turned off. My Dell Latitude has one special port which can do this, but the others do not. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

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?
