In 1994, Intel, Compaq, NEC, digital, northern, IBM, microsoft, etc. seven companies set up the USB Implementers Forum (USB-IF) and on 15 January 1996, intel as formally established USB1.0 interface chipset specification standards. The 2000 Intel announced the official specifications of the USB2.0 Usb1.1 and USB2.0 difference is the transmission speed. Maximum transfer speed usb2.0(high-speed) is usb1.1(full-speed) (480 Mbps) maximum transfer speed (12 Mbps) of 40 times. The Universal Serial Bus (English: universal serial bus, ABBREV: USB) is connected to the computer and an external device port a serial bus standard and an input output interface specifications, is widely used in pcs and mobile devices, message communications products and expansion capabilities to photographic equipment, digital tv set-top boxes, game consoles and other related areas.
- USB2.0:The Universal Serial Bus 2.0 (USB 2.0) released in April 2000 has been one of the most popular I/O connector. Hot plugging , plug-and-play, and High-speed signaling rate (480Mbit/s) are the most significant features.
- USB3.0:The Super-speed Universal Serial Bus 3.0 (USB 3.0) offers the transmission speed of up to 5 Gbit/s, reduces power consumption, and is backward compatible with USB 2.0. As a member of the USB Implementer Forum
- USB 3.1 type C:The new USB interface will replace most of IO in the futture.
- USB 2.0 A's type C: The competitive cost type C design to meet the applcation of smart phone, tablet,external HDD, power bank,PC peripherals, etc.
USB 2.0 A's type C has strengths of price, low temperature rise, low resistance,and high positive force.
