Not sure where to post this one, but I nearly had a house fire last night. Why ?
I've had 3 USB MSD cables plugged into a powered Belkin credit card type 4 port USB hub for about 3 years now, and last night, the Sony Ericsson 300i and Samsung YHJ70 decided to mate at the MSD end, with the consequence that smoke started to rise and the plastic/rubber started to get really hot and melt.
I've now got a useless 300i connecting cable and a slightly charred Samsung connector.
Never seen it mentioned anywhere else so thought I'd put it down here.
How did they decide to mate ? Well, they were just lying there in the general mess on my desk, probably had a drink or two between them, a quick chat and I suppose they got bored and, well, you know how one thing leads to another . . . .
C'mon, I'm being serious above. Exposed data prongs on the 300i and exposed metallic bits on the YHJ70 . . .
Glad you saw it before anything too bad occurred. I'd suggest an annual(at least) spring clean when you should remove all connected cables and examine them. But I'm probably preaching to the converted so I'll just restate that I'm pleased it wasn't more serious.
Why not after three years? It could have been three seconds or thirty years it doesn't matter, the point is they mated somehow and shorted, hence the smoke and burnt out cable and connectors, or are you thinking of something else that I've missed?
