The way that USB uses the driver core is one of the most complex ways, I would not be trying to understand this type of interaction by looking at it :) > The kernel version I used is 2.6.16.1.

What specifically do you want to know about this callback? It is made by the driver core whenever a uevent is about to be sent out by the driver core so that the bus can add specific environment variables that it might want to add to the event. As for reading kernel oops messages, see the kernelnewbies wiki, I'm pretty sure there is already a document there that describes how to do this. thanks, greg k-h -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
