Yes, that's looks like the same problem. 

We haven't got a solution, however we've found that using the 2.6.20 
kernel greatly improves stability.  Using the 2.6.19 kernel I got Oops' 
every day or two, but since upgrading to 2.6.20, it's only disconnected 
once in about 3 weeks.   So it's not perfect, but it's much, much better.

I asked a few questions in the linux-usb-dev mailing list.  And one of 
the developers thought this might have been caused by a bug that only 
got fixed post-2.6.20.  I haven't had a chance to try this yet, but you 
can read about it here:
