在windows 上 uvc设备枚举失败
问题： 在windows插上linux上实现的uvc设备枚举失败
麻烦看下这个枚举失败是为什么？ usts c0004000这个错误是什么引起的
这是 usb hound 抓到数据
这是设备描述符

0xC0004000表示的是The interface was not found.，通你的选择接口失败。
其USB标准请求为：
01 0b 00 00 01 00 00 00
其解释为：
0x01, // bmRequestType: Dir: H2D, Type: Standard, Recipient: Interface
0x0B, // bRequest (Set Interface)
0x00, 0x00, // wValue Alt Setting: 0
0x01, 0x00, // wIndex Interface: 1
0x00, 0x00, // wLength = 0
// 8 bytes
说明在选择接口ID=1时出现在的问题。需这里的接口1是你的VS。故通过醒询其配置描述符如下：

可以看到，你使用了同步的方式来设置，故应该386行的接口下应无端点，但你的有1个。
而471行之后的应用一个同步传输的端点。但你的是BULK传输的。
所以，修改方式有人种：
第一种是直接删除471行之后的所有代码，保留386行中的bulk端点。
第二种是删除386中的端点，把471行中的端点改为同步方式。
以上修改同时得将固件中对应的端点初始化也应修改。
如对以上的不懂，请认真学习同步方式和批量传输方式的实现原理。
