Hey ,

first boot your machine and then plug your scanner or usb hd .Please
see the logs (tail -f /var/log/messages) and see if there any errors
in it.

There are some issues with usb devices please update the rpms like 
kernel ,udev,usbdevices ,initscripts,ramdisk.

I hope after updating the problem will get resolved.
