content: USB C should last quite a while, it's fast enough for everything and has high enough current ability.

content: USB A and USB B are still commonplace and both were invented in 1996. The engineers who designed USB way back when have to take credit for designing such a versatile and long-lasting standard, I'm pretty sure I have a modern day USB mouse/keyboard wireless set that will be enumerating using USB 1.1 still, almost 30 years later.I expect we will see USB C go on for a long time, it will displace USB Micro B due to its comparable form factor but reversible plug & greater functionality, and arguably greater durability. The weird hodge-podges like USB Type B 3.0 (what the hell is this) and USB Micro B 3.0 (even weirder) will die out and no one will remember them for USB C has taken over.

content: Quote from: Ritchievalens on October 03, 2024, 04:32:27 pmI don't think there are any immediate plans to develop a successor to the USB Type C connector any time soon.USB4 v2.0 (which is exclusive to the USB-C cable) is already capable of 80 Gbps symmetrical or 40/120 Gbps asymmetrical.Quote from: tom66 on October 03, 2024, 10:53:58 pmWeird yes, but both of those were (and still are) extremely common for things like printers, scanners and external storage devices.

content: Quote from: Halcyon on October 04, 2024, 12:05:41 amI haven't seen USB 3.0 on a printer or scanner, despite it being over a decade since 3.0 came out. Those are 2.0 at most. Storage devices, yes.

content: Let's keep our terminology straight. A, B, C denote theconnectortypes -- A for hosts, B (in various sizes) for devices, C for both. 1, 2, 3, 4 denote the overallprotocolstandard, defining the transfer speed and other functional aspects.Slightly confusing, the connector types were also defined as part of the various standard iterations. USB 1.0 defined type A and the original, large B connector. If I remember correctly, USB 2.0 defined the mini-B abd micro-B connectors, and USB 3.0 the universal type C connector. But there is obviously no direct correlation between the connector style and the protocol used: One can use USB 1.x over a micro-B connector or 2.x over a USB-C connector.So regarding the OP's question, discussions about a USB4 protocol stack have been ongoing for years and can be Googled. But I am not aware of any interest in a new "type D" connector.

content: Quote from: Halcyon on October 04, 2024, 12:05:41 amI'm referring to the variants of those that carried USB3.0 signals by extending the plug. These peripherals would be backwards compatible with USB2.0 connectors, but it resulted in some strange designs to achieve this.USB C keeps everything in one plug, so it's a considerable improvement IMO. The only problem I see with USB C is you can't naturally determine if one side is host and one side is peripheral, but the prevalence of OTG means that is a feature for some devices.

content: The new type B is not too bad, but Micro-B 3.0 is truly weird. That being said, I have seen this connector on some devices, including one I own. It's not a great connector, but it has the advantage over C that it doesn't support rotation, so device designer has a greater freedom in IC selection.A common workaround is to (illegally) use the much more robust type A socket on upstream facing ports. This is common on 2.5" disk enclosures, which are too small to fit full-size type B and may not want to use type C because see above.

content: Quote from: magic on October 04, 2024, 08:12:02 amNow I understand why I occasionally have to rotate the USB-C plugs if I use USB-C to USB-B 3.0 adaptors...

content: Quote from: ebastler on October 04, 2024, 04:56:04 amThe USB 3.0 standard defined the 9-pin versions of the A and B connectors. Remember, USB 3.0 was released in 2008; USB-C came out in 2014.AFAIK, the C connector is defined separately, since it can be used with USB 2.0 (which itself fully includes the USB 1.1 speeds), or with USB 3.x, or with USB 4.x, or with Thunderbolt, DP, or other alternate modes.USB 3.1 was the first USB standard update to reference USB-C.

content: Yes, "USB-C" has its own specification.'Universal Serial Bus Type-C Cable and Connector Specification". I have the 2.3 spec, which I think is the latest. And then, there are a couple complementary documents.You can find them there:https://www.usb.org/documents

content: Quote from: amyk on October 04, 2024, 02:28:55 amI bought a brand new Epson scanner less than a year ago, it has one of these ports. Although I'm not surprised for imaging devices, those things can generate quite a lot of data at higher resolutions.

Part of the reason it ended up being the 2nd to last Samsung I've ever bought (the last being an Xcover6 Pro that soured me on Samsung altogether for different reasons).
