Requested move 15 February 2019

 * The following is a closed discussion of a requested move. Please do not modify it. Subsequent comments should be made in a new section on the talk page. Editors desiring to contest the closing decision should consider a move review after discussing it on the closer's talk page. No further edits should be made to this section. 

The result of the move request was: moved to USB hardware. (non-admin closure) Celia Homeford (talk) 11:01, 22 February 2019 (UTC)

USB (Physical) → USB connector – Not only is the "P" in "Physical" is incorrectly capitalized (as it isn't a proper name), but the word "Physical" itself is so vague in this context. As such, I propose that "USB connector" is a much more simple and correct name that leaves no room for ambiguity. ~ Arkhandar (message me) 21:48, 15 February 2019 (UTC)

Survey

 * Feel free to state your position on the renaming proposal by beginning a new line in this section with  or  , then sign your comment with  . Since polling is not a substitute for discussion, please explain your reasons, taking into account Wikipedia's policy on article titles.


 * Move to USB hardware - This article is covers several physical/hardware aspects of USB (as opposed to the software), and this title will capture that. IF the intended scope is just the connectors, then USB connector is fine, but information on cabling, ports, hubs, and other devices needs to be removed . The problem is that the overall structure and focus of the articles in this series doesn't seem to be aging well. Very likely the content of this page should be merged into distinct articles for USB 1.0 and USB 2.0 just as there is one for USB 3.0 as well as articles for USB-A, USB-B, and USB-C style connectors. USB or better yet Universal Serial Bus should be a much more simple overview and act more like a WP:BROADCONCEPT. -- Netoholic @ 02:33, 16 February 2019 (UTC)
 * Yes, I was thinking on much the same lines, but you put it better. With the various series of USB, plus that there are ]MicroUSB, MiniUSB and so on, it is not as if there is one type of USB connector or one type of hardware specification for it: and the electronic and hardware characteristics are pretty much siamese twins anyway. For example is the specified maximum length of cable a hardware aspect or an electronic aspect? 178.164.162.144 (talk) 07:22, 16 February 2019 (UTC)
 * Support: per reason above. ~ Arkhandar (message me) 14:29, 16 February 2019 (UTC)
 * Move to USB hardware -In ictu oculi (talk) 18:21, 17 February 2019 (UTC)
 * Support either USB connector or USB hardware, since the current adjective as disambiguator is so odd. Dicklyon (talk) 18:45, 18 February 2019 (UTC)
 * Support I agree that "USB (Physical)" is not a great name. USB connector, USB cabling or USB hardware would all be good choices.  See my comment in the "Discussion" section below. -- RobLa (talk) 01:17, 19 February 2019 (UTC)

Discussion

 * Any additional comments:


 * USB A, USB B both redirect to USB. USB C redirects to USB-C. All of these use USB connectors, indeed are the definitions of USB connectors and their physical (as opposed to electronic) properties. i don't see what good comes of moving this over, if anything USB connector should be a DAB. I agree it is the wrong caps and could be moved to . 178.164.162.144 (talk) 00:47, 16 February 2019 (UTC)
 * Per my comment in the straw poll, I agree that "USB (Physical)" is not a great name. I'd like to propose a few alternatives:
 * A. Rename to USB connector (the original proposal from ). Some content would need to find a new home.
 * B. Rename to USB hardware (alternative suggested by ). That seems to be the best name to capture the scope of the article.
 * C. Split article into USB connector and USB cabling, and merge what doesn't fit back into USB
 * D. Rename article to USB cabling. "cabling" is arguably a superset of "connector", and the USB article deep links to both the "#Connector" and "#Cabling" sections of this article.
 * E. Leave the article at USB (Physical)
 * If I were doing the work, the roadmap I'd propose is Step 1) A, Step 2) C. So, I support 's proposal, but I'm also happy with A, B, C, or D. -- RobLa (talk) 01:17, 19 February 2019 (UTC)

About extension cables -- the kind with Type A plug on one end, and a sort of Type A receptacle on the other
Please edit the article to discuss extension cables for USB -- cables with a regular Type A plug on one end, and a sort of Type A receptacle on the other.

The article has this general statement: "USB cables have plugs, and the corresponding receptacles are on the computers or electronic devices." I suppose one end of an extension cable is an exception to this general statement.

Quite possibly, extension cables aren't, or weren't, in full compliance with USB specifications. Perhaps they are limited to USB 2 speeds. But extension cables are sometimes useful and can easily be bought.

The article has 2 photographs which show extension cables. The opening photograph shows "Various USB connectors along a centimeter ruler..." In this photograph, item "(4) Type-A receptacle" is mounted on a cable, rather than on a computer or device. The 3rd illustration is a photograph: "USB extension cable, male plug on the left, female socket on the right." The photographs are dated 2010 and 2007. USB 3 became common about 2010.

 * Do a Google search on [ "USB 3.0 Extension Cable" ]. I corrected the error in the article. It now reads "USB cables typically have different kinds of plugs on each end, and the corresponding receptacle is usually on the computer or electronic device." --Guy Macon (talk) 19:10, 7 June 2021 (UTC)
 * I don't think I concur. The USB standard specifically forbids extension cables and these cables cannot carry the USB Certified logo (although it is not hard to find them with the logo, but that's trademark infringement). So it's debatable whether such cables are USB cables or are just cables that happen to interconnect with actual USB cables. They're useful things, and they have a place in an encyclopedic article, but it's debatable whether they are USB cables. But I'll allow that many people interpret words more freely than I usually do. I'd like the text to stress a bit more that these are non-standard cables, but I don't care enough to edit it myself right now. Digital Brains (talk) 10:12, 5 July 2021 (UTC)

USB PD rev. 2.0/3.x source power rules
This table is confusing, because each voltage has a white rectangle below the obvious profile. For example +5V has the .1-3 A which gives up to 15W, and then below has a box for all the higher power ratings with 3.0. It might be useful to have a caption explaining that the higher power modes are possible at that voltage, but that the power is capped at the lower mode level. or something like that.

4-Pin Mini B
Unless I missed it, there's no mention at all of 4-Pin Mini B connectors. These were definitely a thing - early digital cameras, for example, used them. I remember having a hard time trying to source a replacement. If someone could find out if they were part of the official standard / where they fit in / if and when they were replaced by 5-Pin variant, that’d be a good addition. 80.5.118.143 (talk) 15:13, 28 May 2022 (UTC)
 * No, they're not part of the official standard, they're a proprietary solution some manufacturers used for a while. However, I think they deserve mention in the article, just like we mention "extension cables" that are specifically forbidden by the standard even. Digital Brains (talk) 16:12, 28 May 2022 (UTC)
 * I agree. For historical accuracy and full documentation, there should be a section on proprietary variations. The 4-pin Mini B is in fact still in use. It is very difficult to find references to this connector type. Aftermacx (talk) 20:42, 7 September 2022 (UTC)

Physical size of USB-A connector
This article does not show the outer dimensions of the USB-A plug. — Preceding unsigned comment added by 194.53.184.154 (talk) 15:52, 16 April 2019 (UTC)


 * I'm also missing any notes about "spacing specifications". Specifically if multiple type-A female connector are in a row (horizontal line), what is the minimum distance? I have some sticks that seems overly wide (blocks the neighboring connector), so I wonder whether those sticks are within specification. Uhw (talk) 13:40, 22 January 2023 (UTC)
