Take a look here: http://www.tnkernel.com/usb_fw_upgrader.html
I use this, and it works well, except for the issue of the trial
driver code that times out after 4 hours. But, this just means you
need to reboot a couple of times a day.

>From the description, it seems that you can use
libusb-win32 and rewrite the bootloader PC application using libsub-win32 device
driver and API. You may be able to make it work under Linux
with libusb as well.

But Microsoft does not support it within Windows, so it is not
really an advantage unless you can use the above-mentioned
host driver according to their licenses.
You can always use other USB class, like CDC or vendor
specific class.
I have read about many great bootloaders that users of this group have
created. I will have to use or write my own bootloader that will allow
to make firmware upgrade via USB. Is there any open standard of such
protocol, to program via USB? Maybe someone have this bootloader
already written, or documents how it works?
