The reason is that although the device is detached, normal stop and unbind operations are commanded. Avoid these unnecessary operations when the device is detached (state is USB_STATE_NOTATTACHED) so as not to get the error messages.
I am sorry, but this is a layering violation. You are looking at an internal state of the USB layer to surpress logging -ENODEV. If you think these messages should go away, filter for ENODEV where they are generated. Regards Oliver
