Indeed that was the problem. We changed quite a bit in dfu-util to get
the actual informations from the USB functional descriptor. And it
seems that was not provided correctly from the u-boot DFU
implementation before. Good to have that fixed.

We are really careful not to introduce regressions when going forward
with dfu-util but some stuff is just way to problematic to keep when
moving on.

I wonder where you actually got such an old version of dfu-util. We
work together with packagers to get new versions in all recent
distros. Might be worth to fill a bug about updting it for yours.
