* The FX2 chip does not give us a zero length read at end of frame.
* It does, however, give a short read at the end of a frame, if
* neccessary, rather than run two frames together.
*
* By choosing the right bulk transfer size, we are guaranteed to always
* get a short read for the last read of each frame. Frame sizes are
* always a composite number (width * height, or a multiple) so if we
* choose a prime number, we are guaranteed that the last read of a
* frame will be short.
*
* But it isn't that easy: the 2.6 kernel requires a multiple of 4KB,
* otherwise EOVERFLOW "babbling" errors occur. I have not been able
* to figure out why. [PMiller]
*
* The constant (13 * 4096) is the largest "prime enough" number less than 64KB.
*
* It isn't enough to know the number of bytes per frame, in case we
* have data dropouts or buffer overruns (even though the FX2 double
* buffers, there are some pretty strict real time constraints for
* isochronous transfer for larger frame sizes).
