Make the question precise. I assme there are two usb ports in my notebook at left and right separately. When I plug mouse into left usb port, I get 2-1.1:1.0 right usb port, I get 2-1.2:1.0 I want to know whether it is right that no matter how many times I reboot the machine, the test result above will be the same.And if it will be the same, then why it will be the same. -- 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
