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