The gadget is not initialized here (so the dfu-util -l shows no
output).

After transfer it shows information about proper alt settings.

This is correct behaviour, but I had discussion about this with Tom and
we agreed, that it would be nice to have "dfu-util -l" exporting from
very beginning the alt setting information.

Frankly, I had too much other work to implement it.

However, I think, that it would be a very useful feature (e.g. to get
alt settings layout at HOST to facilitate automated flashing).
