Why does nobody talk about how cheap USB borescopes can fry your laptop port?

I plugged a $12 borescope into my work laptop to check a hidden corrosion spot on a Cessna wing spar and it shorted out the USB port completely, cost me $150 for a motherboard repair and a whole afternoon of downtime.

Honestly, a $15 powered USB hub saved me after the same thing happened with my old laptop.

Yeah, I started using a cheap powered USB hub after that happened to me.

@sean_walker45, did the hub actually protect your laptop or just its own ports?
