Then, in September 2017, USB 3.2 was released. There are four versions of USB 3.2: Gen 1×1, Gen 1×2, Gen 2×1, and Gen 2×2. By design, it is difficult to insert a USB plug into its receptacle incorrectly. The USB specification requires that the cable plug and receptacle be marked so the user can recognize the proper orientation. [1] The USB-C plug however is reversible. USB cables and small USB devices are held in place by the gripping force from the receptacle, with no screws, clips, or thumb-turns as other connectors use. a b "USB 2.0 Specification Engineering Change Notice (ECN) #1: Mini-B connector" (PDF).

In short, almost every device that includes a PCB (printed circuit board) will likely have at least one type of USB port on it somewhere. PCB USB connectors and related components are cheap to buy, and easy to mount in a variety of ways including panel, surface, through-hole, and cable mount. There are so-called cables with A plugs on both ends, which may be valid if the "cable" includes, for example, a USB host-to-host transfer device with two ports. [3] This is, by definition, a device with two logical B ports, each with a captive cable, not a cable with two A ends.

USB Type-C: USB Type-C is a newer and versatile connector that is becoming increasingly popular. It is reversible like Micro-USB but has a smaller form factor. USB Type-C cables can be used for charging devices, data transfer, and connecting various peripherals. They support faster data transfer speeds and can deliver more power. Howse, Brett.

So, USB 3.0 and USB 3.1 Gen 1 are essentially the same and have a top data transfer speed of 5 Gbps. Then, in July 2013, USB 3.1 Gen 2 was released, with its top data transfer speed at 10 Gbps. In May 2021, the USB PD promoter group launched revision 3.1 of the specification. [58] Revision 3.1 adds Extended Power Range (EPR) mode which allows higher voltages of 28, 36, and 48 V, providing up to 240 W of power (48 V at 5 A), and the "Adjustable Voltage Supply" (AVS) protocol which allows specifying the voltage from a range of 15 to 48 V in 100 mV steps. [71] [72] Higher voltages require electronically marked EPR cables that support 5 A operation and incorporate mechanical improvements required by the USB Type-C standard rev. 2.1; existing power modes are retroactively renamed Standard Power Range (SPR). In October 2021 Apple introduced a 140 W (28 V 5 A) GaN USB PD charger with new Macbooks. [73]
You can only compare up to four products at a time.
It is safe to say that almost all electronic devices, including smartphones, laptops, tablets, desktops, Bluetooth speakers, and so on, rely on USB ports and cables for various functions. USB-B is pretty much only used on large devices, like scanners or printers. Visually, this connector looks almost square. Most of these are USB-B to USB-A cables, though some newer devices have moved on from USB-B to smaller options, like Micro-USB or Mini-USB. Micro-USB
