关于USB Hub Testing Overview"

问题
-
Hi whql team:
现由于马上要对我司的USB HUB进行WHQL测试,由地不知测试环境,所以查看了下USB Hub Testing Overview相关内容,但查看之后,对如下所示内容的理解并不是很清楚,不知你们是否可以提供帮助?谢谢!
1:Hardware requirements
The following hardware is required for USB Hub testing.
- One USB Hub under test (two test devices are required for USB serial number support)
- One external USB 2.0 high-speed hub, self-powered
- One external USB 1.1 full-speed hub, self-powered
- One Cypress Full-Speed USB 2.0 Compliance test board
- One Cypress Low-Speed USB 2.0 Compliance test board
The low-speed and full-speed Cypress functional compliance test boards can be purchased directly from the USB Implementer’s forum:
2:Test system configuration
- The device(s) under test must be connected via an external USB 2.0 hub (not directly connected to the client test system)
- Ensure that the hub under test is recognized by the client test system before proceeding
- If the device supports a USB serial number, be sure to attach the additional test device to the external hub before scheduling the USB Serial Number test
答案

usb hub dtm 测试中:
- One Cypress Full-Speed USB 2.0 Compliance test board
- One Cypress Low-Speed USB 2.0 Compliance test board
- 这两个要求项目是什么意思。

不过关于WHQL方面的学习机会好像很少啊(根本就没有),不过在此还是想问一下,关于USB HUB的测试描述你处能否简单的帮忙描述一下啊,因为从字面上理解的话,我处根本就不知道如何操作测试!目前我处只测试过UFD(U盘),不知道USB HUB的测试操作是否是与其一样的!

- One Cypress Full-Speed USB 2.0 Compliance test board
- One Cypress Low-Speed USB 2.0 Compliance test board
对于如上所示的每条USB HUB的硬件测试条件,我处部分可以理解,但是部分不能理解,所以还是烦请你们帮助一下,谢谢了!
1:第一条与第二条总的来说应是如果测试的USB HUB是不同带序列号的,必须用二个USB HUB测试机进行对比测试,其中一个是接在外置的USB HUB上后在连接电脑,另外一个USB HUB直接连接电脑进行测试!
2:而对于2所示的One external USB 1.1 full-speed hub, self-powered 我处一直是不明白道底是什么意思,另外3 4条也是一样,

原来是因为英文理解有问题,这个我恐怕没办法一一帮你理解。毕竟别人能提供的帮助非常有限。
由于logo requirement更新特别快,翻译的精度和实时性都特别差,所以建议你熟悉一些基本的test terms.
One USB Hub under test (two test devices are required for USB serial number support)
这个意思是一个USB hub在测试的时候要求有两个USB测试设备接在上面。
self-power 指外接供电。 也就是有电源适配器的usb hub. high-speed and full-speed are usb term, I am not sure how to express it in Chinese either. 这些方面应该是IHV的专长了。你可以查看你的product spec看看是不是符合。
