If there is nothing in dmesg or /var/log/messages the disk is not 
visible to the system. I had the same problem once. The USB plug at the 
disk side was a type B connector and I had inserted this plug with the 
wrong orientation, i.e. turned around 180°. I certainly needed some 
force to do that but it was possible. After I connected the plug 
properly the disk worked.
