I'd say the first step is to turn debug logging on - I see it's 
disabled in the standard .config. First option below USB mass storage 
support. Hopefully you will get the identical behaviour and also an 
explanation in the logs.

I'm not familiar with that device, what other modules does it load? 
grepping the kernel source doesn't return anything useful, and 
because everything else seems to work for you that indicates the 
problem is local to that model and/or it's drivers.

I fear you will coaster a few more blanks before this is over, put it 
down to your personal contribution to the revolution :-)
