I assumed it was some either some BS article telling us about a BS AI usb product
....OR a BS audiophile article trying tell us how crosstalk from your usb cable will ruin the sound and we need a 800€ ultra high density thbtq insulated core USB 7.0 type Zed cable.
USB 3.x actually does produce 2.4GHz interference, which could cause stuttering if you use Bluetooth and your adapter is too close to the USB port/hub or a USB 3 device. Shielding for USB 3 devices and cables does matter, and lack of shielding is part of why Chinese devices from Amazon (or worse, Temu/AliExpress) are so cheap. That's about as crazy as it gets though, sorry.
I believe cable length is included in the emarker data too, probably useful in conjunction with PD PPS to identify whether the cable is damaged based on the resistance/voltage drop
Would be nice if there was something that could read the outputs/inputs on proprietary USBc implementations. Like my Asus tablet that only charges at the full 100w with the OEM charger.
