Last one for today: In "USB" we have '-' (27) and 'No' (345) in parallel.
We should be more consistent here.
According to the general rules it should be
- : not applicable / hardware not present
but we have several other fields where we also have 'No' in use today, instead of '-'.
Too late now for me to think about this.
Just come up with a proposal, you'll do the right thing ;-)
