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