我用at89s52和D12想做USB通讯，为什么插到电脑上没反应，goodLink灯是亮的？

鱼丫丫啊

如题，我是用的at89s52，D12，想实现和pc的USB通讯，电路图就是按照您所说的原理电路图焊接的，为什么插到电脑上不会提示发现新硬件，但是goodLink灯是亮的？

baiheee

如果goodlink灯是常亮，证明设备已经枚举成功，没有提示发现新硬件，是因为之前已经在同一个USB接口插过设备并成功枚举并安装了驱动，再次在同一个USB插上同一个设备就不会再提示发现新硬件了。可以在插上设备的情况下在设备管理器里删除这个设备，然后再重新插，或者换一个USB插口也会提示发现新硬件的。

如果不确定设备是否枚举成功，可以打开设备管理器看，还可以用bushound监视一下枚举过程（不过要求对协议比较熟才行）

上面的数据不全，没有看到请求设备描述符的部分，这部分在不停地SET FEATURE和GET STATUS，设备枚举有问题。

鱼丫丫啊

后来我又把电路修改了一下，A0接高电平，ALE接At89s52的ALE，然后把outportb和inportb又改回为ZLG的程序，结果能抓到GET DESCRIPTOR，但后面还是说是无法识别的设备
设备描述符为：

[code=cpp]code USB_DEVICE_DESCRIPTOR DeviceDescr =
{
  sizeof(USB_DEVICE_DESCRIPTOR), //设备描述符长度,= 12H
    USB_DEVICE_DESCRIPTOR_TYPE, //设备描述符类型,= 01H
    // 0x10,0x01, //协议版本,= 1.10
    0x00,0x01,
    USB_CLASS_CODE_TEST_CLASS_DEVICE, //测试设备类型, = 0DCH
    // 0,
    0, 0, //设备子类,设备协议
    EP0_PACKET_SIZE, //端点0最大数据包大小,= 10H
    0x71,0x04, //PHILIPS公司的设备ID

ZLG提供的程序是DMA模式的，与本站实例不一样，注意它们的区别。另外，看了您的设备描述符，这是测试类，Windows系统没有提供这类设备的驱动，需要另外提供，那您的驱动是自己写的还是用的别人的？注意驱动里的PID和VID要和固件一致，端口配置也要和固件一致！

鱼丫丫啊

还真是PID的问题，固件的PID和驱动的PID不一致，改了过后就可以正常枚举，驱动也装成功了。

不过还有人问题需要麻烦版主，我做了一下通信实验，怎么用busHound抓包，只能抓到DO呢？
