Belkin USB 2.0 Cable USBA-USBB in Charcoal 1.8m

Product Information

To reduce confusion, the USB-IF also intends to do away with numbered USB versions in the future, instead encouraging device makers to refer to a port's top speed, as in "USB 20Gbps." We're in favor of that. Le souci de compatibilité des câbles, des ports, des versions logicielles, des adaptateurs ou des solutions propriétaires n’aurait dès lors plus cours. Le fameux " cable management" – et les tiroirs remplis de ces prises dont on a oublié l’utilité – pourrait bien lui aussi disparaître. Impossible pour l’heure de prédire avec exactitude quelle norme l’emportera.

Micro USB:So-called Micro USBversions of both USB-A and USB-B also exist - smaller versions than their base counterparts, popular on mobile devices. Older but now obsolete "mini USB" versions can also be found on many old devices.

A和Type-B根据支持的USB标准不同，又可以分为USB 2.0和USB 3.0标准USB接口。根据接口的颜色，我们很容易区分该接口是支持USB 2.0还是支持USB 3.0的。Type-A型接口也是我们日常生活中最常见的USB接口，广泛应用于鼠标、键盘、U盘等设备上，Type-B型则常用于打印机、特殊显示器等设备上。 2、Mini USB接口 The date the document that announces the end-of-sale and end-of-life of a product is distributed to the general public. Applications of USB Technology in the Commercial AV Market: Key Considerations and Solutions Comments Off on Applications of USB Technology in the Commercial AV Market: Key Considerations and Solutions Micro USB接口，属于Mini USB的下一代规格接口，Micro USB接口的插头采用了不锈钢材料，插拔寿命提高为10000次，相比Mini USB接口，在宽度几乎不变的情况下，高度减半，更为小巧。Micro USB接口也可分为Micro-A和Micro-B两种，样貌如下：

USB was originally designed for computer peripherals: keyboards, mice, external disk drives, printers, scanners, cameras, and the like. More recently, USB has become a versatile connector for audio and video devices like speakers, microphones, monitors, and webcams. USBのコネクターは、接続する機器などによって複数の種類があります。さらに、利便性を向上させるために新たな種類が作られることもあり、今後も種類が増えていくかもしれません。以下で、おもなUSBのコネクターを5種類ご紹介します。 ・USB Type-A But USB-C is different—and perhaps it's even as truly universal as its acronym (Universal Serial Bus) suggests. USB-C ports are now found on all manner of devices, from simple external hard drives to high-end laptops and, after a long holdout session, the Apple iPhone. While every USB-C port looks the same, not every one offers the same capabilities. USB-C may now be ubiquitous, but it doesn't serve the same functions everywhere. Not by a long shot. This broad acceptance by the big dogs is important, because it's part of why USB-C has been so readily accepted by PC manufacturers. Contrast this with the earlier Apple-promoted (and developed) Lightning connector, which had limited acceptance beyond Apple products and is facing obsolescence, thanks in no small part to USB-C. USB-C is so broadly accepted that the European Union, hoping to simplify digital life, will require devices to use it for battery charging starting in 2024. Whether it’s a USB-A, B, or C, their data transfer speed are determined by USB versions. All three types of USB ports can run USB versions of 1.1, 2.0, 3.0, or 3.1. The higher the USB version is, the faster the speed it brings.USB-C is electrically compatible with older USB 3.0 ports. But because of the shape of the newer port, adapters or cables with appropriate plugs are indeed required if you want to connect anything that doesn't have the USB-C oval shape.

Article intéressant qui résume bien l'histoire et l'avenir de l'USB et plus généralement des chargeurs pour les néophytes. Deux ans après la mise en service de la solution lightning d’Apple, en 2014, l’USB-C voit le jour. Si la quantité de données transmise reste d’abord la même, ce connecteur a l’avantage d’offrir un courant deux fois plus intense (3A) que son prédécesseur, mais, surtout, d’être réversible et donc de pouvoir être branché dans n’importe quel sens (que ce soit celui de la prise ou du câble complet). If it’s old or has been roughly handled, it might not work right anymore. Change the cable and see if that resolves the issue.

USB-C is an industry-standard connector for transmitting both data and power on a single cable. The USB-C connector was developed by the USB Implementers Forum (USB-IF), the group of companies that has developed, certified, and shepherded the USB standard over the years. The USB-IF counts more than 700 companies in its membership, among them Apple, Dell, HP, Intel, Microsoft, and Samsung. Or open the device manager to scan for hardware changes and disable and re-enable the USB controller if you have a Windows PC. Malgré cela, le problème central avait été déplacé plutôt que résolu. Si l’impulsion d’origine visait un standard simple d’usage, le chaos des anciennes connectiques avait été remplacé par une nouvelle jungle de formats USB. Certes, ils ont eu le mérite de combiner les câbles d’alimentation avec ceux convoyant les données, mais pas beaucoup plus. Il n’y a pas eu d’homogénéisation, pas plus que de modèle universel et unique. Confused yet? Further complicating matters: The number scheme around USB 3 has been in flux, which has made references to these ports something of a swamp. Until recently, many USB-C ports carried the USB 3.1 label ("USB 3.2" was not yet a thing) in Gen 1 and Gen 2 flavors, and some spec sheets continue to reference the older name, along with SuperSpeed branding. In a confusing twist, the USB-IF decided to eliminate the use of "USB 3.1" in favor of these various flavors of USB 3.2, as outlined below in this handy decoder chart... Or, niveau praticité, avantage écologique et économie de matériaux, ce dernier l’emporte forcément. Du moins, il le fera s’il ne consomme pas davantage de terres rares ou de métaux précieux, de moins en moins disponibles.

As you can see above, some USB-C ports use the USB 3.2 Gen 2x2 specification, with maximum speeds of 20Gbps. The USB-IF decided on "2x2" because this standard doubles the data lanes within a USB-C cable to achieve the 20Gbps transfer speed. These ports have not been widely available. They will likely go by the wayside in favor of another emerging flavor of USB-C port, supporting USB4, which the USB-IF has announced will eventually support data speeds up to 120Gbps. news ■2018年7月16日 2018REMEMBER OF CLASSIC CONTEST開催 7月16日北九州市芸術劇場で、「2018REMEMBEROF CLASSIC CONTEST」が開催され、無事終了致しました。 大会の成績は　⇒ 2018kseiseki.pdf へのリンク ■2017年7月15日 2017WEST-JAPAN　CONTEST開催 7月15日熊本市中央区黒髪の熊本市男女共同参画センターはあもにいで、「2017USBB ALL-JAPAN CONTEST」が開催され、大盛況の中、無事終了致しました。 大会の成績は　⇒ 2017kseisekin.pdf へのリンク ■2016年10月9日 2016ALL-JAPAN CONTEST開催 10月9日東京都品川区大井の品川区立総合区民会館きゅりあんにて、「2016USBB ALL-JAPAN CONTEST」が開催されました。今回より「RONNIE COLEMAN CLASSIC CHALLENGE CUP」への選手派遣選考の大会となりました。 大会の成績は　⇒ tseisekin.pdf へのリンク ■ 2016年7月3日 2016WEST-JAPAN CONTEST開催 7月3日熊本市中央区黒髪の熊本市男女共同参画センターはあもにいで「2016WEST-JAPAN CONTEST」が開催され、大盛況の中、無事終了致しました。大会を通じ、熊本地震で被害に遭われた方々に少しでも勇気と希望を与えられたなら、ＮＰＯ法人USBB-JAPANとして大変うれしく思います。 大会の成績は こちらへ⇒ kseiseki.pdf へのリンク ■ 2015年11月22日 2015ALL-JAPAN CONTEST開催 11月22日福岡市中央区天神のＦＦＧホールで「2015ALL-JAPAN CONTEST」が開催され、大盛況の中、無事終了致しました。 USB-B port isn’t as wide as a USB A port, and it also has a tiny rectangular hole in the middle. It is usually not used on modern computers. But it is commonly found on printers, routers, and scanners. USB-C Si l’on résume, l’USB-C est réversible, assez petit pour équiper tous les appareils et assez puissant pour alimenter en courant la grande majorité des machines actuelles. Dans le même temps, il propose un taux de transfert de données parmi les plus élevés pour l’heure. Tous les flux audios, vidéos, de données et électriques peuvent ainsi passer par un seul et même câble, en théorie pour tout simplifier et quel que soit le périphérique.
