本文介绍了USB序列号测试失败(USB复合设备HID类)的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述


我们无法通过启用序列号的USB HID复合设备的USB序列号测试(Windows 10 HLK)。如果我们禁用序列号,它可以通过。但我们需要在启用序列号的情况下测试我们的设备。你能帮我吗?我们尝试了另一家
公司的HID复合设备以及相同的结果。我们还禁用了所有设备和集线器电源管理设置,但仍然失败。注意:在Windows 8 HCK中,我们可以通过USB串行测试。



DUT:HID类USB转UART / I2C Master 控制器板


- 全速HID类USB设备

- 提供UART和I2C主接口






设备管理器:  DUT序列号是有效数字。



我们已经禁用所有电源管理但仍然失败。




谢谢,

解决方案

您好,


看一下以下内容:

USB序列号测试


< p style ="background:white; margin:10px 0px"> 问题


此测试中存在一个已知限制,如果被测设备提供序列号,则两个实例
必须在D0中才能使测试正确读取序列号字符串。 failure pattern是一个错误语句,说序列号字符串不是NULL终止,这是不正确的,测试实际上根本无法检索它。


解决方案


controller board

- Full speed HID class USB device
- Provides UART and I2C Master interface

Device Manager:  DUT Serial Numbers are valid numbers.

We already disabled all power management and still FAIL.

Thanks,

解决方案

Hello,

take a look a the following:

USB Serial Number Test

Problem

There is a known limitation in this test such that if the device under test provides a serial number, both instances must be in D0 for the test to correctly read the serial number strings. The failure pattern is an error statement saying that the serial number string was not NULL terminated, which is incorrect, the test actually wasn’t able to retrieve it at all.

Solution

Ensure that the device is in D0 when the test runs. The test run only takes a few seconds so this can be as simple as re-attaching in the devices immediately before scheduling the test so it executes before the suspend timeout occurs, or using the device during the test (move/click input device, access network, read/write files, etc.)
