Hmmm.  That fixed the problem of the polls occuring too frequently, but
now I see again intervals that are larger than 256 ms.  In the most
recent test there are two intervals of 512 ms and one of 2048 ms.

PS: Is the databook for the DWC2 controller available for download?  
I'm going on vacation starting next week, and I might want to have a 
little light reading to take along.  :-)
