Article over at ZDnet. Huh, I did not know that there even was a code.
In case that link ever evaporates into the aether, here's the main part:
- 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.
- White: These are first-generation devices -- USB 1.x -- with the slowest potential transfer speeds that don't typically exceed 12 Mbps. They're also some of the most common, found on devices that don't require data transfer or high power delivery.
- Yellow: These ports can support either USB 2.0 or 3.0, and are "always on", meaning they can supply power even when the device they're connected to is off.
- Orange: Like yellow, but with support for USB 3.0. Always on. You might see these on your pair of headphones.
- Blue: Supporting USB 3.0 SuperSpeed technology and above, blue ports identify a device capable of fast data transfer: up to 5 Gbps (that's 5,000 Mbps) -- a significant jump from previous generations. Besides laptops, you'll see blue ports on thumb drives and external storage.
- Teal: Just like blue, but denoted as USB 3.1, supporting faster transfer speeds of up to 10 Gbps.
- Red: These are the newest and fastest devices available, categorized as USB 3.1 Generation 2 and USB 3.2. They support another significant increase in data transfer speeds -- up to 10-20 Gbps. Red USB ports are also always on.
Yes, blogging has been light lately. Working on that part.
