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.

D'ailleurs d'après mes propres tests, les câbles USB-C de marque Apple ont un taux de charge et de transfert supérieur que d'autre marque sur du matériel Apple. 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.

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).

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.

Mini USB接口，是一种小型的USB接口，其指标与标准USB相同，但是加入了ID针脚（用于区分设备是主机还是外设），以支持OTG（On The Go，该功能允许在没有主机的情况下，实现设备间的数据传送）功能。Mini USB接口主要分为Mini-A和Mini-B两种，样貌如下： Or open the device manager to scan for hardware changes and disable and re-enable the USB controller if you have a Windows PC.
