I ran into this article online last week, http://www.laptopmag.com/articles/how-to-find-safe-usb-type-c-cables it discusses how a bad USB Type-C cable fried a Google engineers equipment, including a Chromebook Pixel. It also covers another issue when another bad Type-C cable drew too much power from a laptops port killing them. I highly suggest you read the article, but if you don’t have time then in summary; when a low quality, uncertified USB Type-C cable was used the incorrect resistance value for Type-C configuration causes the device to think it’s connected to a 3amp USB Type-C connection. Drawing 3A from a 500mA or 900mA port is not a good idea; the extra current draw damaged both devices. This issues reared its ugly head when using a USB Type-C to USB Type-A uncertified cable.
How do I avoid this you ask!!!!??? The article (and I agree) notes that typically cables from named brands are typically high quality and tested and the USB-IF also maintains a list of certified cables.
Choosing a certified solution is the lower risk path you can take. This is also the best advice to take when selecting USB IP for your next project. A certified USB IP solution reduces the design risk as you have the confidence that the IP has passed rigorous testing in a real world environment. Synopsys just announced that our 10 Gbps USB 3.1 IP has passed USB-IF certification and actually is the first IP solution to pass USB-IF certification. Is you are considering a USB 3.1 design, Synopsys is the lowest risk choice for an IP solution.
That’s one pretty USB 10G eye
