USB-是英文UniversalSerialBUS（通用串行總線）的縮寫，而其中文簡(jiǎn)稱為“通串線”；支持設(shè)備的即插即用和熱插拔功能。USB是在1994年由Intel、NEC、Compaq、DEC、IBM（、Microsoft、NorthernTelecom多家公司聯(lián)合提出制定的，并于1994年11月11日發(fā)表了USBV0.7版本，到現(xiàn)在已經(jīng)發(fā)展為3.1版本。USB具有傳輸速度快，使用方便，支持熱插拔，連接靈活，獨(dú)立供電等優(yōu)點(diǎn)；而USB認(rèn)證又叫USB-IF認(rèn)證，它就是USB ImplementersForum(USB-IF)推行的一個(gè)自愿性的標(biāo)志性認(rèn)證。
The certification tests for USB peripheral devices can be divided into three categories. The first is electrical characteristics testing to verify the signal quality of the product under different application architectures. This is followed by a functional test to check higher-level product details, such as the level of support required by the standard and device enumeration capabilities. Finally, the product interoperability test is used to determine the interaction between the product under test and other USB devices.
