> Given that this was posted back in January and nobody else has chimed in with a "my computer too" or "oh my goodness that's how my peripherals all died" post, I'm guessing it's an isolated failure.

Plenty of people have. My laptop did the same thing back in January, frying two separate U2F devices (at first, I thought the key was faulty, but it fried two different keys on different ports).

I replaced the laptop and haven't thought about it since, until two days ago, when my replacement laptop fried a display adapter.

Its rare but I know someone who fried at least 4 devices. We found this post when trying to figure it out, wish we had thought of putting it on HN!

There are at least 93 other people who clicked "I have this question too" on the post.

This thread is filled with people complaining about the same thing

Just reading or were you writing to the SD card? Flash memory gets hot during write cycles.

this happens to me too, thought it was normal... I'll have to avoid using it for now.
