Re: Firecracker and USB-Serial

No reading comprehension problems.  I addressed that the standard is
insignificant because it is violated to such an extent that it is useless.

Saying "Just buy the apropriate (sic) cables and if they plug in they work."
without qualifying it that this is in case the vendor just happens to follow
the official standard, when you know that they don't is a load of crap.

I suppose that you would also be willing to say "following the speed limit
means you won't get passed."
