Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.Switch on a usb scanner 2.Inspect /var/log/messages to see the disconnect. xsane, for example cannot connect to the scanner. Hardly surprising :-) 3.

The scanner and xsane then work normally. I doubt that this bug is in hotplug itself. Sorry, I don't have time to investigate further. I will attach a fuller log.
