在使用USB与外设通信中,我用DeviceIOControl来读,写数据,都是系统自带的API函数.

Declare Function DeviceIoControl Lib "kernel32" (ByVal hDevice As Long, ByVal dwIoControlCode As Long, _
lpInBuffer As Any, ByVal nInBufferSize As Long, lpOutBuffer As Any, _
ByVal nOutBufferSize As Long, lpBytesReturned As Long, _
lpOverlapped As Long) As Long

请给出HID类USB设备的dwIoControlCode的具体值列表?

你需要安装DDK自己查看

打开MSDN，索引“DeviceIoControl”，会有相关帮助，如果你能编译运行testUSB的VC工程，也许会有一些启发。
