This graph has some faults and is misleading. For example for the following aspects:

• Generally mismatches/simplifies operation modes with specification version
• USB4 defines many more operation modes
• 'USB4 20Gbps' does not exist as an operation mode
• USB4 2x2 is not interchangeable with USB 3.2 2x2 as indicated by the logo
• logos for USB 3.x and USB4 are different

@ZH8000:

1. & 2. This table was made with consumers in mind, i.e. it tries to alleviate the confusion (for which simplifications have to be made) of previous marketing name schemes (often still being used, despite the newer recommendation for the names https://web.archive.org/web/20230510092046/https://usb.org/sites/default/files/usb_data_performance_language_usage_guidelines_september_2022.pdf and https://www.usb.org/sites/default/files/usb-if_integrators_list_marketing_name_guidance_january_2023.pdf) so that the consumer can understand what they are paying for (e.g., when comparing different smartphone models). It wasn't meant to be a detailed table, e.g., containing all operation modes for USB4, only meant to contain the names/logos that can often be seen in media/print. Maybe moving the table with the paragraph to another place in the article could make the designated use clearer.

3. If you search for USB4 20gbps, you will find some product descriptions mentioning it. Also, I got those marketing names from https://www.usb.org/sites/default/files/usb4_language_product_and_packaging_guidelines_final__0.pdf . That means I had to include somehow this certain name.

4. As in the recommendation from https://web.archive.org/web/20230510092046/https://usb.org/sites/default/files/usb_data_performance_language_usage_guidelines_september_2022.pdf , it is stated that for reduced confusion, clear communication of the performance signaling that a product delivers is important. So I (perhaps wrongly) decided to use 1 logo, so that it would be the most up-to-date. By my understanding (might be wrong, but as this whole thing is a big mess without concise, clear and up-to-date info, it's all I can muster) USB4 2x2 and USB 3.2 2x2 won't have separate logos, but will be marked by the same logo.

5. The logos used are packaging logos, from https://www.usb.org/sites/default/files/usb-if_usb_performance_logo_usage_guidelines_final_20230320.pdf . If there are any more up-to-date/correct logos, please link their high quality version in the reply to this comment (preferably from official source).

If there are still some things needing to be changed, the best result that can arise from this discussion would be bullet points that describe where & what to change to what (with sources by which the need for the change is based on).

This help request has been answered. If you need more help, you can ask another question on your talk page, contact the responding user(s) directly on their user talk page, or consider visiting the Teahouse.

Need advice whether I can now remove the disputed warning template from the table. I explained the reason for the table being as it is, but I am not getting any replies/counterarguments/tips on changing the table. GravityCore (talk) 14:14, 19 November 2023 (UTC)Reply

Helpers alerted by the {{help me}} template are not going to weigh in on content issues. It's up to you to determine whether a sufficient consensus exists for what you wish to implement. If you are not getting enough response here on this talk page, the next place to go is usually to the talk page of one of the WikiProjects whose banners appear at the top of the page. After that , it might appropriate to open an RFC - but sometimes it's best to go ahead and make the change and see if that smokes out some responses from other editors. You could even include a phrase like "seeing no objections on the talk page..." as part of your edit summary. — jmcgnh^{(talk) (contribs)} 19:29, 19 November 2023 (UTC)Reply

On 30 October, an edit was made (Revision as of 13:46, 30 October 2023) to insert "hubs" as an additional type of device to which USB connections can be made, making three types. Unfortunately the article now reads:

... Type-A (upstream) and Type-B (downstream) connectors, found on ''hosts'', ''hubs'', and ''peripheral devices'', respectively, ...

So "respectively" is ambiguous. "hosts" goes with Type-A, and "peripheral devices" goes with Type-B. "hubs" goes with ??? Rather than fixing it myself, I would prefer that the edtitor do it. Frankly, I don't see any good reason for complicating the issue by introducing "hubs." 47.184.152.29 (talk) 19:50, 18 November 2023 (UTC)Reply

No, all three kinds of devices are part of the specification, you can not remove one of them. I removed the 'respectively' term. -- ZH8000 (talk) 20:40, 18 November 2023 (UTC)Reply

That's definitely an improvement. According to USB 3.1 and 3.2, "USB device" covers both "hubs" and "peripheral devices," so it is still possible to remove "hubs," but the bigger problem is now gone so thanks for that and your other work. 47.184.152.29 (talk) 01:49, 19 November 2023 (UTC)Reply

I just made an edit removing a broken source link. Hope that was good one? Olivia Harry (talk) 21:02, 2 January 2024 (UTC)Reply

I have not seen "Fabrics" stated following USB-C in any of the cited articles. If I'm missing something, whoever entered or approved that insertion has to support it, because it makes no logical sense. User 194.230.148.168 has undone my deletion of that word in this context, stating "Read the Specs": which specs has not been cited that makes this at all clear?--Toolnut (talk) 20:52, 14 April 2024 (UTC)Reply

The citation contains "USB4 V2 with Errata and ECN through June 2023 - CLEAN.pdf" in the zip file (currently "USB4 V2 with Errata and ECN through September 2024- CLEAN.pdf" as the file has updated since then) both of which are official and contain "USB4 Fabric". Neither the article nor the source explain this usage of "fabric", and for readers of an encyclopedia (which is expected to be read by non-experts) should include an explanation or use more layman terms outside of the quotation taken from the standard. — Preceding unsigned comment added by 2600:1700:2940:1DD0:0:0:0:2B (talk) 04:57, 17 December 2024 (UTC)Reply

On "Available connectors by USB standard", the 3.0, 3.1, and 3.2 Micro-A connector should have a Remark explaining the image is reversed from the others. 2600:1700:2940:1DD0:0:0:0:2B (talk) 04:13, 16 December 2024 (UTC)Reply

https://www.moddiy.com/pages/USB-2.0-USB-3.0-USB-3.1-USB-3.2-USB-4.0-Connectors-and-Pinouts.html ( near bottom ) seems to have a diagram for this *COMMON* type of connector. Unfortunately, I do not own the work. Also, no scale. ShaReeLi (talk) 15:36, 25 December 2024 (UTC) . . . the existing diagram under 2.0 Revised ( column ) seems to be nearly the same, but stuff around the edges obscures the shape.Reply
