Mmh,  "usbcore" is blacklisted, so try to modprobe it and see if the
USB stuff start working again, if yes modify your
/etc/hotplug/blacklist accordingly. Probably you have something broken
on your /etc/modutils/aliases about your scanner (modprobe: Can't
locate module scanner), but this should be unrelated to your
problem...
