More likely than not hot-plugging the keyboard is what damaged it. The other possibility is ESD; which also has the potential for damaging any uncased board like the PineA64, or the Raspberry PI... for that matter.
But two things: 1) plugging a $120 keyboard into an open SBC is insane; and 2) blaming keyboard damage on the engineering efforst of the Pine team is no fair, especially without proper testing nor corroboration.
read gsh » Wed Nov 12, 2014 10:20 pm as an example of Raspberry Pi built in ECD protection, I know I read in it the technical specification and news reports but do not have the time to find it for you. Do not search for the word "hardened" as that will be RPi3 and we do not know which he is using
1) plugging in a USB complaint device into a USB compliant socket in not insane, problem only occurs when standards have been ignored. Not that I know if either device is compliant.
2) In the event that pine USB is not compliant then, yes they could be said to be at fault if the socket was presented as being compliant
All this is academic, the point I was making is that without actually being present so you could test the socket and keyboard for compliance and check that both devices are ECD protected can anyone have a valid opinion, anything else would be mere conjecture.
Remote diagnosis of this fault is impossible given the limited amount of information available from OP and so I am saying that rather than post an opinion based upon nothing but conjecture, that the OP actually gets someone competent to make an assessment.
With the information available in this thread how could legitimately state "... no way plugging it into the PineA64 killed it, no technical way.", the fact is you haven't tested either device nor where you present at the time the fault occurred.
