Isn't USB host mode by definition internally powered, and USB device mode by definition externally powered? An externally powered USB host mode sounds quite non-standard. If you allow that mode, how does the system know whether it should be a host or a device when external power is applied; it sounds like this new mode completely breaks the ability to connect the tablet to a PC and use it for Android application development, or MTP (Media Transfer Protocol) to download pictures/movies. > Do you happen to know anyone responsible for the Ubuntu Nexus7 kernel?

Sorry, I don't know what kernel they're using; the best place to ask would be the Ubuntu project itself. -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
