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. High-speed devices must also be capable of falling-back to full-speed as well, making high-speed devices backward compatible with USB 1.1 hosts ...
The Hi-Speed USB logo. USB 2.0 was released in April 2000, adding a higher maximum signaling rate of 480 Mbit/s (maximum theoretical data throughput 53 MByte/s [25]) named High Speed or High Bandwidth, in addition to the USB 1.x Full Speed signaling rate of 12 Mbit/s (maximum theoretical data throughput 1.2 MByte/s). [26]
Most of the listed rates are theoretical maximum throughput measures; ... 1.2/0.075 kbit/s: ... USB 1.0 low speed:
A number of extensions to the USB Specifications have progressively further increased the maximum allowable V_BUS voltage: starting with 6.0 V with USB BC 1.2, [42] to 21.5 V with USB PD 2.0 [43] and 50.9 V with USB PD 3.1, [43] while still maintaining backwards compatibility with USB 2.0 by requiring various forms of handshake before ...
Apple Lightning to USB-A cable. Lightning is an 8-pin digital connector. Unlike the 30-pin dock connector it replaced (and USB Type-A and -B connectors), it is reversible. [22] Most Lightning devices only support USB 2.0, which has a maximum transfer speed of 480 Mbit/s or 60 MB/s. With USB 2.0, only one lane is in use at a time.
eSATAp combines the functionality of an eSATA and a USB port, and a source of power in a single connector. eSATAp can supply power at 5 V and 12 V. On a desktop computer the port is simply a connector, usually mounted on a bracket at the back accessible from outside the machine, connected to motherboard sources of SATA, USB, and power at 5 V ...
It is an important consideration that in common language (and often product marketing), USB 2.0 is used as synonymous with high-speed. However, because the USB 2.0 specification, which introduced high-speed, incorporates the USB 1.1 specification such that a USB 2.0 device is not required to operate at high speed, any compliant full-speed or ...
Both PS/2 and USB allow the sample rate to be overridden, with PS/2 supporting a sampling rate of up to 200 Hz [5] and USB supporting a polling rate up to 1 kHz [3] as long as the USB mouse runs at full-speed or higher USB speeds.
