I tried to connect keyboard directly to the USB port on mainboard and also to my notebook. Notebook has only one mouse connected. Unfortunately this does not help. If I understood right, this is hardware error? So if this would be bandwidth problem, then Windows XP will also have same problem? Or this is not hardware error and it works with Windows because Widows has another way to compute available bandwidth? -- Sergey -- 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
