Connectors[edit]

The first paragraph launches into discussion of sizes (standard, mini, micro) and speeds (Low Speed, Full Speed, High Speed, SuperSpeed & SuperSpeed+). Following that is the paragrgraph explaining topology (Unlike other data buses ...) with the upstream/downstream distinction. Logically the order of the two paragraphs should be reversed; topology should be explained before connector size and speed.

The explanation of upstream/downstream orientation is there and the explanation of A/B is there but the relationship between orientation and A/B is left implicit. For any reader who doesn't already understand the subject, explicit would be better than implicit.

Comments? Any objection to improvements? Thanks, ... PeterEasthope (talk) 14:38, 10 November 2019 (UTC)[reply]

@PeterEasthope: Sorry this hasn't gotten any response in three years. You certainly make valid points and have my support. Can you tell whether these issues still need to be addressed? — voidxor 23:19, 23 May 2023 (UTC)[reply]

Just swapped the two paragraphs as suggested earlier. Let's see whether the change is tolerated before investing effort to explain the relationship of orientation to A/B. Thanks for the interest. ... PeterEasthope (talk) 13:58, 25 May 2023 (UTC)[reply]

Very good, thanks! You can wait if you like, but I get the sense from the history that there's not a lot of editors here. I would suggest appending, at minimum, something like "per talk" to your edit summaries so that anybody viewing your edits can find this discussion with your detailed reasoning. — voidxor 16:51, 25 May 2023 (UTC)[reply]

Connector colors[edit]

There are no sources for these colors, except for citation number 9 which is just an Amazon product page link. An Amazon link is not a legitimate source. Anyone can make one and put whatever they want there.

Can we get better sources for these colors and their purposes? 76.69.148.67 (talk) 19:28, 11 October 2022 (UTC)[reply]

In fact, that link is now dead. Looking back at an archived copy, nowhere in the product description did it explain the green port. Clearly somebody's original research, which I have now removed.

Like you, I'm looking for a reference to support the alleged white=USB 1.x, black=USB 2.0 association that's shown in the illustrated table on USB. — voidxor 00:00, 24 May 2023 (UTC)[reply]

USB UC-E6[edit]

I couldn't find anything about USB UC-E6 in the article. Are there other USB UC connectors? UC=Ultra Compact? --2A02:810A:1E40:A14:1826:696D:92DD:D906 (talk) 10:10, 25 October 2022 (UTC)[reply]

This looks like another nonstandard connector to me. See any of the other discussions on this talk page. — voidxor 00:20, 24 May 2023 (UTC)[reply]

10 Pin SuperSpeed MiniUSB Type B[edit]

They did exist here's a port and cable 172.116.113.102 (talk) 21:37, 4 March 2023 (UTC)[reply]

And your question or suggestion is...?

Whatever that is, it's nonstandard. See § About extension cables -- the kind with Type A plug on one end, and a sort of Type A receptacle on the other and § 4-Pin Mini B above for similar discussions about how much coverage the nonstandard junk that comes out of China deserves. Seems like a rabbit hole to me. — voidxor 00:16, 24 May 2023 (UTC)[reply]

Cable differences between USB 1.x and 2.0?[edit]

The Cabling section is a little terse. Can anybody tell me if the cable standards (e.g. wires, twists, shielding) changed at all from USB 1.x to USB 2.0, other than the slight change of the maximum allowed length? I realize that was 23 years ago. Even if there was no real change (in other words, a pre-2000 USB version 1 cable would be within spec for 480 Mbit/s USB version 2 connections), I think that would be worth mentioning. — voidxor 18:00, 25 May 2023 (UTC)[reply]
