Your tests were made with the default device, which is "plughw", which
automatically converts sample formats.  I.e., when you play a S24_BE
file, the data is byte-swapped by ALSA because the device claims it
supports LE only.

Please do all your tests again ;-) with the "-D hw:0" parameter.

Please note that S24_?E is 24 bits data packed into four bytes, while
S24_3?E is 24 bits in three bytes.  USB devices support the latter
only.

Your effort is appreciated, but we already know that the Transit uses
DFU to download its firmware.  (DFU is a specification published by
the USB-IF.)  fxload is for EZ-USB chips, not for DFU-compatible ones.

I've written a DFU loader
http://prdownloads.sourceforge.net/usb-midi-fw/madfu-firmware-0.1beta3.tar.gz?download
which does the same as the Windows loader.  Unfortunately, it doesn't
work because the 2.4 kernel gets confused when the device resets
itself.
