...But some devices like my old sony and my Aura HD detects when the adaptor can give more and then ask: is this a computer or do you only want to use the charging....

i don't think that bit is quite correct. I have a an amazon fast charge adaptor & cable that they sell for silly money ( but which came free with my HDX tablet). When I plug my aura HD into that it just charges - there's no is this a computer issue. & that's on FW 3.3
Conversely, if I plug my Kindle HDX into the Kobo branded adaptor+hard wired cable that came with my Kobo Arc tablet - the Kindle warns - you are using a (crap) slow charger - even though the output rating printed on the kobo charger (5v 2 amp) is higher what amazon advertise! The kobo charger must have one of the optional charging wires disabled I guess.
