Pine64 $15 card killed my $120 keyboard

Not that I'm disagreeing or disputing what you are saying, but....that seems a stretch.

I assume you've done a bit of troubleshooting with it plugged into your original computer..looked to see if it was recognized in desk ice 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

I'd be inclined to plug a cheap standard keyboard into the Pine and fire it up. Test both ports, and verify it works..or not.

So to confirm..does your PC device manager (assuming a windows machine) see the K70 keyboard and its just non-responsive? Or does it not even show up as a device?

You could pop the top of the K70 and see whats going on with it if it appears it definitely has an issue, but not sure of your technical skill level and if you're confident doing that.
