I tested the kernel from our lucid git repo. It works fine with the JMircon USB 
storage disk. But we finally find this is not a specific fsl-imx51 issue. It is 
a Lucid issue.

I tried the JMircon USB disk on my Lucid laptop. It does not work at all as well 
as my Babbage board. But this USB disk works on fine on Karmic Laptop and Karmic 
Babbage board.

I also tried Karmic .31 kernel on my Lucid Babbage board. So I suspect some user 
space applications changes introduced a regression.
