I'm not an expert on the logging module, but I believe the propagate
attribute is not inherited by children.
I actually found that it's pretty easy to just manually set this, since
the logging module uses singletons:
----
log = logging.getLogger('usb')
log.propagate = False
----
I do that in my application and it allows us to use the root logger
without any USB chatter.
The only drawback to this method is that it does depend on the 'usb'
string. I think a class method like usb.core.getLoggerName() that
returns 'usb' would be a nice way to alleviate the dependency on another
module's built-in strings.
Thanks,
