Hmm... I just compared the original DFU and the upgrade DFU using the
verify option:

./dfutool verify ITSE_00003_07_IBM_BDC_Firmware128_Rev310.dfu
Filename        ITSE_00003_07_IBM_BDC_Firmware128_Rev310.dfu

Might the missing product and vendor ID be the problem with upgrade
file? Can/should I try to change those?

Cheers
