A USB cable, by definition, has a plug on each end—one A (or C) and one B (or C)—and the corresponding receptacle is usually on a computer or electronic device. The mini and micro formats may connect to an AB receptacle, which accepts either an A or a B plug, that plug determining the behavior of the receptacle.
If they are hot swapped, the devices must be similar enough that the driver running on the host system recognizes and can be used with the new device. Otherwise, the new device will not function properly. While this is seldom an issue with standard keyboard devices, the host system rarely recognizes the new device attached to the PS/2 mouse port.
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). 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 ...
The result is that some UVC 1.5 devices that also support UVC 1.1 work correctly. macOS macOS ships with a UVC driver included since version 10.4.3, updated in 10.4.9 to work with iChat. Windows Windows XP has a class driver for USB video class 1.0 devices since Service Pack 2, as does Windows Vista and Windows CE 6.0.
It is intended primarily to save cost in low-bandwidth human interface devices (HID) such as keyboards, mice, and joysticks. Full speed (FS) rate of 12 Mbit/s is the basic USB signaling rate defined by USB 1.0. All USB hubs can operate at this rate. High speed (HS) rate of 480 Mbit/s was introduced in 2001 by USB 2.0.
The Linux kernel has supported USB mass-storage devices since its 2.4 series (2001), and a backport to kernel 2.2.18 has been made. In Linux, more features exist in addition to the generic drivers for USB mass-storage device class devices, including quirks, bug fixes and additional functionality for devices and controllers (vendor-enabled functions such as ATA command pass-through for ATA-USB ...
USB communications device class (or USB CDC) is a composite Universal Serial Bus device class. The communications device class is used for computer networking devices akin to a network card, providing an interface for transmitting Ethernet or ATM frames onto some physical media. It is also used for modems, ISDN, fax machines, and telephony ...
