我也觉得纳闷。刚开始我怀疑硬件有问题。可是能够读芯片ID，能够收，能够发，我觉得是不是就说明硬件正确呢?
是这样的，枚举成功的时候抓到的数据是：一次get device descriptor,一次set address,接下来get device descriptor,get config descriptor. 枚举不成功的时候情况就比较多，也是按照上边的顺序，有时候是set address后pid check failed.有时是第二个get device descriptor.有时是get config descriptor 后pid check failed.有时是都发送接收正常了，但还是没有枚举成功。 现在我没有抓到的数据。等我抓下来发上来。 楼上的兄弟，这样交流比较慢，而我比较着急。不知道是否可以直接发信给你? |

偶尔能枚举成功?怪事.如果能枚举成功的话,说明你的固件应该没问
题,但大多数情况不行?你能不能将成功的和不成功的数据都采集到, 然后对比一下,看看有什么不同. 还有,不会是硬件故障吧? :( |

就是偶尔可以枚举成功。checkview可以看到枚举成功。出现查找驱动程序。大多数情况下则不能。

你说的偶尔能枚举成功是什么意思?

多谢。我跟踪一下看。
我现在的情况是这样的：偶尔能够枚举成功。 这就可以说明get descriptor.set address等函数没有问题。 这样的话判断是初始化的问题。可是初始化就设置几个参数，我觉得也不应该有问题。 现在我不知道问题出在什么地方。没有办法下手了。 |

CLEAR FEATURE 是HOST发给HUB的命令,跟你的设备没关系,但在枚举
过程中不应该出现. 建议你看看在你回复 12.0 CTL 80 06 00 02 00 00 09 00 GET DESCRIPTOR 898.1.0 12.0 DI 09 02 4a 00 01 01 00 a0 32 ..J.....2 898.2.0 后是否又收到中断,什么中断? |

没关系
应该是标准请求你返回的参数不对 |
