 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？
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？

那是因为驱动程序已经安装好了，所以不会再提示发现新硬件。可在硬件管理器里将这个设备删掉，再插入设备，就会出现提示了！

灯闪几下就灭了吗？如果这样是的话是没有成功枚举，可用BUS HOUND抓一下枚举数据，看看枚举到哪一步失败的

上面的数据是全的，确实是收不到请求设备描述符的部分
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 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
0x66,0x01, //设备制造商定的产品ID
0x00,0x01, //设备系列号

 小小的成功了
我用的就是本站的实例，后来发现好像PID跟驱动不符，又修改了一下，可以装驱动了，最后枚举成功了。可为什么我删除硬件之后再重新插入，还会说是无法识别的设备呢？

哈哈，换了台机器就成功了，可能是主机USB接口的问题
不过可能又要麻烦强哥了。我按照本站 如何与HID设备通讯（一）中的实例做了一下实验，怎么用busHound抓包，只能抓到DO呢？

还是不行啊
我又重新试了一下，还是不行啊。下面是第一次执行RUN后busHound抓到的数据。我再执行RUN后DO也抓不到了，是不是因为第一次根本没把数据发出去，缓冲区是满的，所以第二次根本就抓不到数据？
