RE: Specs are one thing

I wasn't talking about whether the data worked or not, or even if a power cycle was needed before things worked again. I was talking just about damaging the USB port. I would be surprised if an Intel board were damaged when connected to a short. I feel the same about audio power amplifiers. These can oscillate into certain loads, in addition to current limiting problems. In either case, I don't want to have anything to do with them, no matter how good they may sound under other circumstances.

I had a 1960's vintage aircraft transceiver and it blew the RF output transistor when running with the antenna disconnected. (Actually, the problem was a bad contact, not installation error.) This unit had been made in southern California. A few years later the company went out of business after the manufacturing plant burned to the ground. Later, I bought a nice German transceiver that worked reliably for over 20 years. It turns out that the German aircraft certification requires running test units continuously for 30 minutes into open loads and into shorted loads. It then must immediately pass its certification tests.
