USB规范的版本命名简直可以说臭名昭著了，除了故意扰乱用户之外想不出任何解释。
现在，USB-IF组织对于USB-C数据线的命名进行了重新梳理规范，倒是相当的简洁明了。
The naming of the version of the USB specification is almost infamous, and there is no explanation other than deliberately disturbing the user.
Now, the USB-IF organization has reorganized the naming specifications for USB-C data cables, which is quite concise and clear.
According to the new regulations implemented on March 15, USB-C data cables will be classified from two dimensions: rate level and power level, and manufacturers are required to give clear identification to facilitate consumers to distinguish and choose.
The main contents of the new regulations are as follows:
1, USB-C to USB-C data cable in the future is divided into four rate types, in order is 480Mbps, 5Gbps, 20Gbps, 40Gbps, no longer emphasize the USB specification version, but only distinguish the supported rates.
At the same time, USB-IF no longer accepts authentication for USB 3.2 Gen2 10Gbps Type-C to USB-C data cables.

2, USB-C to USB-C data cable in the future only support two maximum transmission power, respectively 60W and 240W. The original 100W power was eliminated, and 240W was replaced.
3. Any USB-C to USB-C data cable must use the transmission rate and power identification specified by USB-IF.
You can then firmly attach the label with the specified logo on the data line, or you can directly mold the logo on the outer mold.
480Mbps rate of data cable, do not label the rate, only the power. For the other three kinds of data, the rate and power must be marked at the same time.

4. When the USB-C data cable is certified, the manufacturer must first apply for a special logo from the USB-IF, and then send a sample with the logo.
Before performing the test, the certification laboratory also first checks that the sample is using the logo correctly.

根据3月15日起实施的新规，USB-C数据线将从速率等级、功率等级两个维度进行分类，并要求厂商给出明确标识，方便消费者进行区分和选择。
新规的主要内容如下：
1、USB-C to USB-C数据线今后分为四种速率类型，依次是480Mbps、5Gbps、20Gbps、40Gbps，不再强调USB规范版本，而只区分所支持的速率。
同时， USB-IF不再接受USB 3.2 Gen2 10Gbps Type-C to USB-C数据线的认证。

2、USB-C to USB-C数据线今后只支持两种最大传输功率，分别是60W和240W。原来的100W功率取消，240W取而代之。
3、任何USB-C to USB-C数据线，必须使用USB-IF规定的传输速率、功率标识。
可以再数据线上牢固粘贴印有指定Logo的标签，也可以在外模上直接模印Logo。
480Mbps速率的数据线，不标注速率，只标注功率。其他三种数据的，必须同时标注速率、功率。

4、USB-C数据线认证时，厂家必须先向USB-IF申请专用Logo，然后送测带有Logo的样品。
认证实验室在进行测试之前，也会首先检查样品是否正确地使用了Logo。
