USB-C seems like a really bad standard if the cable can destroy expensive electronics.
EDIT: Even if the cable is wired and built correctly (which is apparently difficult for manufacturers to get right), cables fray and tear all the time. I foresee a lot of dead electronics upcoming.
- tantalor 11y agoBut the cable was not standard USB-C... that's the problem.
- digi_owl 11y agoWell when the cable has GND and VBus crossed, standard compliance issues goes out the window. This was a straight factory QA failure.
- tomswartz07 11y agoIt's not the standard that's bad, it's the actual wiring of it. That's akin to saying: The US power grid is a bad standard because I wired up my house wrong and it burned down.
- JoshTriplett 11y agoThat's like saying Ethernet, VGA, and many other standards are bad because http://www.fiftythree.org/etherkiller/ http://www.fiftythree.org/etherkiller/ shows cables that directly pump AC power into them.
- cesarb 11y agoIt's not USB-C. The same thing would happen with USB-A/B, or any other standard which provides power with a well-defined polarity. The mistake was in the simplest part of the standard: the pair of wires which carry the voltage reference (GND) and the main voltage (Vbus), a pair of wires which exist since the original USB standard, and in many many other standards (ever used a "PS/2" keyboard? guess what, two of the pins are GND and Vbus!). As for cables fraying, the most common result is an open (an unconnected wire). If two of the wires get damaged at the same time, you might get a short (and the USB standard mandates that a short causes no damage to devices). But reversing a pair of wires? It's ridiculously unlikely that fray and tear on a cable not only severs a pair of wires, but also reconnects them backwards!
