Why cannot you read USB device?
// previous codeh = CreateFile(completeDeviceName, GENERIC_WRITE,// | GENERIC_READ, FILE_SHARE_WRITE,// | FILE_SHARE_READ, NULL, OPEN_EXISTING, // FILE_FLAG_OVERLAPPED, 0, NULL); // current code h = CreateFile(completeDeviceName, GENERIC_WRITE | GENERIC_READ, FILE_SHARE_WRITE | FILE_SHARE_READ, NULL, OPEN_EXISTING, // FILE_FLAG_OVERLAPPED, 0, NULL); // Now I can readfile USB device port |

你首先发表.设备描述符与驱动程序的关系.我才会告诉你,否则告诉你也是浪费.因为我一修改描述符.ReadFile and WriteFile 就不成功.仙林电子与周立功的描述符相比.仙林电子的少了端点1的描述符.况且驱动程序不变.你起码要做点贡献.不光只是拿...,否则开发资料哪里来?

上贴不是端点最大包的大小为0的错,而是传输查询间隔应该为0,因为是BULK传输. |

我已经把周立功的描述符放到正常的ARM程序中测试.ReadFile and WriteFile are normal.证明我对D12的操作掌握不够多.因此应该集中精力了解D12的操作.

PDIUSBD12编程 PIPE00 ~ PIPE03
PIPE00 and PIPE02 are all readfile handle.PIPE01 and PIPE03 are all writefile handle.Whichever PIPE handle for DeviceIoControl is corresponding to EndPoint0.How Strange. |

本例子驱动程序是异步IO操作.用函数BulkUsb_BuildAsyncRequest()建立异步读写请求.因此CreateFile,ReadFile and WriteFile OVERLAPPED 不能为NULL.

PDIUSBD12速度慢,设备句柄有时需要连续打开数百次才能成功!
