Amazon Basics USB 2.0 A-Male to B-Male cable with Gold-plated connectors (3 m/10 Feet), Black

Product Information

While this can be expected in a mobile platform such as a tablet or a phone, desktop PCs and laptops often will not support dual roles. The Mini-USB connectors (Mini-A, Mini-B, Mini-AB) were introduced for mobile devices, but they were quickly replaced by the thinner Micro-USB connectors (Micro-A, Micro-B, Micro-AB). There is also the USB Type B Mini, primarily found on digital cameras, USB hubs, and external hard drives, and the USB Type B Micro which is used by modern Android phones. A type of USB3 Tunneling architecture where the Enhanced SuperSpeed protocol is extended to allow operation at the maximum bandwidth available on the USB4 Link. From short lengths for close connections to longer ones for more extended reach, there is a USB A to B cable suitable for every situation.

The Type-C connector, also known as USB-C, is not exclusive to USB, is the only current standard for USB, is required for USB4, and is required by other standards as well, including modern DisplayPort and Thunderbolt. Examples of peripherals that are connected via USB include computer keyboards and mice, video cameras, printers, portable media players, mobile (portable) digital telephones, disk drives, and network adapters.USB has no such requirement as it was designed for peripherals closely associated with a host computer, and in fact it connects the peripheral and host grounds. SuperSpeed (SS) adds two additional pairs of shielded twisted data wires (and new, mostly compatible expanded connectors) besides another grounding wire. Among them it supports Alternate Mode, which allows transporting other protocols via the USB-C connector and cable. The Capsule Plus provides high-speed USB charging for laptops and other devices; making it ideal for office and homeworking.

For mice and keyboards with dual-protocol support, a passive adapter that contains no logic circuitry may be used: the USB hardware in the keyboard or mouse is designed to detect whether it is connected to a USB or PS/2 port, and communicate using the appropriate protocol. However, if you have a USB 3 device, you can still use that same USB cable to connect it to an old computer that only supports USB 2. USB4 products may optionally offer interoperability with the HDMI, MHL, and VirtualLink Alternate Modes. introduced support for High Speed USB (in addition to Full Speed), allowing greater bandwidth for multi-channel interfaces, higher sample rates, [70] lower inherent latency, [71] [67] and 8× improvement in timing resolution in synchronous and adaptive modes. USB-C (Type-C) is a single connector that replaces all Type-A and Type-B connectors ( legacy connectors), so when both sides are modern equipment with USB-C ports they negotiate which is the host (A) and which is the device (B).Often referred to as “male”, as they plug into a “female” port, it is important to understand that there are two elements of USB standard to consider; the physical connector shape and the underlying protocol (speed).

You'll find USB Type-A ports in most modern computers, laptops, game consoles (like the PlayStation, Xbox, and Nintendo Switch), smart TVs, streaming media players, and other devices. USB was designed to standardize the connection of peripherals to personal computers, both to exchange data with and to supply electric power. The PCM2906C employs SpAct™ architecture, TI's unique system that recovers the audio clock from USB packet data. For example, a USB-to-parallel-port converter might work well with a printer, but not with a scanner that requires bidirectional use of the data pins. It was introduced around 2006, and before the advent of Alternate Mode over USB-C it was the only way to connect displays via USB.These and other differences reflect the differing design goals of the two buses: USB was designed for simplicity and low cost, while FireWire was designed for high performance, particularly in time-sensitive applications such as audio and video. Media Transfer Protocol (MTP) was designed by Microsoft to give higher-level access to a device's filesystem than USB mass storage, at the level of files rather than disk blocks. The wide range of transfer speeds available from a USB interface suits devices ranging from keyboards and mice up to streaming video interfaces. eSATA, like USB, supports hot plugging, although this might be limited by OS drivers and device firmware. In addition to his extensive writing experience, Chris has been interviewed as a technology expert on TV news and radio shows.

It is reversible and can support various functionalities and protocols including USB; some are mandatory, many optional, depending on the type of the hardware: host, peripheral device, or hub. It has largely replaced interfaces such as serial ports and parallel ports and has become commonplace on a wide range of devices. Device Firmware Upgrade (DFU) is a vendor- and device-independent mechanism for upgrading the firmware of USB devices with improved versions provided by their manufacturers, offering (for example) a way to deploy firmware bug fixes. If the devices are different generations---if you plug a 20-year-old USB drive into a modern PC, for example---they may perform slower, but they will work. Charging docks supply power and do not include a host device or data pins, allowing any capable USB device to charge or operate from a standard USB cable.GBd [95] and the 11-bit–to–7-trit translation provides a theoretical maximum transmission speed just over 40. Another use for USB mass storage devices is the portable execution of software applications (such as web browsers and VoIP clients) with no need to install them on the host computer.
