"It turns out that it actually means something. There's a standardized color scheme that communicates information about that device's capabilities. Mind blown? If you never noticed this, you're not alone. Most USB devices work fine on any compatible port, but they may not be optimized for optimal performance. For example, if you've noticed a mouse seems to work better in one port over another, it's not in your head. One probably supports USB 3.0, and the other doesn't."
"Despite the fact that they share a universal port shape, all USB-A and USB-C devices are not created equal, with potentially very different transfer speeds, power transfer, and generations on similar devices. Even two USB-C ports right next to each other on the same laptop could have very different capabilities when it comes to data transfer speed and power delivery. Let's take a look at what they mean."
"There are seven major color that indicate a device's generation and what kind of data transfer speeds you can expect. If you have a rare device with a color not listed here, let me know in the comments. Black: Denoting USB 2.0, this is the second most common you'll see on devices of all types, supporting speeds of up to 480 Mbps."
USB port colors follow a standardized scheme that communicates device generation, data transfer speeds, and power-delivery features. Most USB devices function on compatible ports but may not deliver optimal speeds or power when connected to non-matching ports. Identical-looking USB-A or USB-C ports can support different transfer rates and power levels, even on the same laptop. Seven common colors indicate expected performance: black for USB 2.0 (up to 480 Mbps), white for USB 1.x (up to 12 Mbps), yellow for always-on power support (USB 2.0 or 3.0), orange for always-on USB 3.0 support, and blue for USB 3.0 SuperSpeed technology.
