If it is as you said concerning the undefined state of the USB power across a reboot, that information is very helpful for me.

I am not saying it is not happening in MS/commercial world... -- 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
