[RichardG] has noticed a weird discrepancy \u2013 his Ryzen mainboard ought to have had fourteen USB3 ports, but somehow, only exposed thirteen of them. Unlike other mainboards in this lineup, it also happens to have a USB-C port among these thirteen ports. These two things wouldn\u2019t be related in any way, would they? Turns out, they are, and [RichardG] shows us a dirty USB-C trick<\/a> that manufacturers pull on us for an unknown reason.<\/p>\n

On a USB-C port using USB3, the USB3 TX and RX signals have to be routed to two different pin groups, depending on the plugged-in cable orientation. In a proper design, you would have a multiplexer chip detecting cable orientation, and routing the pins to one or the other. Turns out, quite a few manufacturers are choosing to wire up two separate ports to the USB-C connector instead.<\/p>\n

In the extensive writeup on this problem, [Richard] explains how the USB-C port ought to be wired, how it\u2019s wired instead, shows telltale signs of such a trick, and how to check if a USB-C port on your PC is miswired in the same way. He also ponders on whether this is compliant with the USB-C specification, but can\u2019t quite find an answer. There\u2019s a surprising amount of products and adapters doing this exact thing, too, all of them desktop PC accessories \u2013 perhaps, you bought a device with such a USB-C port and don\u2019t know it.<\/p>\n

As a conclusion, he debates making an adapter to break the stolen USB3 port out. This wouldn\u2019t be the first time we\u2019re cheated when it comes to USB ports \u2013 the USB2 devices with blue connectors<\/a> come to mind.<\/p>\n<\/p><\/div>\n
