I assume you've done a bit of troubleshooting with it plugged into your original computer..looked to see if it was recognized in device manager, verified you didn't have an issue with the usb cable, tried a different usb port, etc?

Just for grins I did a quick google and I see a lot of incidents mentioned related to K70 keyboards suddenly dying, nothing related to the Pine.
I did as I said on my first post

... no way plugging it into the PineA64 killed it, no technical way.

sorry.

It was working perfectly seconds before, the possible explanation is that my board being bare bones (as I didn't receive my case yet) my hand could have touched one of the pins while I plugged it.

That is, not without doing something that would kill the pine64 at the same time... like shove 12v into it instead of 5v! That would toast both it and anything plugged into the USB ports for sure!!!  Big Grin
I'm using it with the power supply sent by the pine team

If you truely feel that the Pine destroyed your keyboard then just get someone qualified in electronics to test the port, the fact is that whilst a lot of people have got used to the idea that say a PC will fail safely, the pine is not a PC. It is instead a homebrew board that unlike the RPi is not aimed directly at school children interested in electronics, thus I would suggest may be missing a lot of protection that comes as standard with say a PC not least being a case. 

Personally I would not have risked using an expensive keyboard and especially not one that has has failure problems or higher current drain to power lights/onboard electronics such as is normal for gaming keyboards.

So as no one here can actually say with certainty what is coming out of your USB port without testing it, especially the "pine apologist", I would have it tested by someone with the tools and competence to say if the keyboard was destroyed because it was plugged into a faulty USB port

The USB port may check out fine and it be, as your say, down to ECD which can damage pretty much any unhardered/un-isolated ICs, in which case you would need to show that pine suggested you run the board without basic ECD protection, not least of which is keeping your fingers away from the board whilst it is in operation.
