Hi,

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.
