Apparently, hotplug/udev isn't working for you. Read the INSTALL  
document that came with the sources and follow the instructions in  
'Build and install' paragraph 6 on how to temporarily work around  
this. We probably can't help you fix this however, you'd have to ask  
the people from Ubuntu to do that.

Best regards, Arjen
