我找到问题了，
主要是我的固件配置描述符的问题 我用的是ARM ads，本来是9个字节的结构，ads偏偏搞成了10个字节 本来是6个字节的结构，ads又搞成了8个字节。我快疯了！ 不过分还是给的，毕竟主动帮忙了么 ;) |

或者贴出来 |

但是配置描述符在windriver里面可以看到啊，已经受到了啊
calc_device_info_size 对应着什么描述符的信息啊？能否问一下？ |

从下面开始，就出错了
calc_device_info_size: bad configuration descriptor usb_unconfigure_device: entered, pdo = 8155c2d0, cfg desc = 0x81453c08 get_usb_info: usb_configure_device failed with status 0x20000012 start_device: Failed querying device info (pdo 0x8155c2d0, type -2) dispatch_pnp: 'IRP_MN_REMOVE_DEVICE' (0x2), pdo 0x8155C2D0, DEVICE Usb_device_detach: device handle 0x814536b8 not found in device list usb_unconfigure_device: entered, pdo = 8155c2d0, cfg desc = 0x0 |
