You need custom drivers for this device anyway, so it might be a better
idea to let the software do a decent job.  (You might want to add to the
USB packets a header with the current settings and the actual amount of
entropy; in that case there is less danger that anybody thinks this data
is a perfectly random bit stream.)

And why are you calling it a whitener instead of a randomness extractor?
The former name could imply that the output looks random, but has less
than 100% entropy.
