Hi Lukasz, I bet transmission is performed, but with the default settings of dfu. The DFU function descriptor is completely ignored.
An easy way to verify it is to check if the DFU version of the device is the same one as the one stored in the descriptor. Same with the transmission block size. It might work, but only by accident. I sure hope I'll have time today to send my captures as well.
