read10的数据包（原码)
d12的端点2只有64个字节.在read(10)的请求中要求返回8个逻辑块的数据，而每个块有512个字节，共4096个字节.当我传输512个字节是没有问题，但超过512个字节传输4096个时，就出错了，只完成了一半.
平斑竹帮帮忙,谢谢!!!!!!!!!! ^_^ 部分代码: typedef union _CBWCommandBuf { struct _operation{ unsigned char Head[4]; unsigned long tag; unsigned long transferlength; unsigned char datadirection; unsigned char SCSILUN; unsigned char CBW; union _OpenationData{ unsigned char OperationCode; struct _Inquiry{ unsigned char OperationCode; }Inquiry; struct _ModeSense{ unsigned char OperationCode; unsigned char DisableBlockDescriptor; unsigned char PageCode; unsigned char Reserved1; unsigned char ParameterLen; unsigned char Control; }modesense; struct _writeread{ unsigned char OperationCode; unsigned char Reserved1; unsigned long LogicalBlockAddress; unsigned char Reserved2; unsigned int TransferLength; unsigned char Control; }read10,write10; }CommandCode; }OperationData; unsigned char DataBuf[64]; }CBW_COMMANDBUF; typedef union _epp_flags { struct _flags{ unsigned char configuration; unsigned char setup_packet; unsigned char outhead; unsigned char write; unsigned char read; unsigned long LogicalBlockAddress; unsigned long TransferLength; }bits; unsigned long value; }EPPFLAGS; struct{ unsigned char Head[4]; unsigned long tag; unsigned long transferlength; unsigned char datadirection; }CSWsection; CONTROL_XFER ControlData; CBW_COMMANDBUF CbwCommandBuf; EPPFLAGS bEPPflags; unsigned char Databuf[10240]; void USB_submit(void) { unsigned char i; if(ControlData.wLength>ControlData.wCount) ControlData.wLength = ControlData.wCount; sendcommand(ControlData.in); sendcommand(0xf0); senddata(0x00); senddata(ControlData.wLength); printf(\"out: \"); for(i=0;i<ControlData.wLength ;i++) { printf(\"%2x \",*(ControlData.pData)); senddata(*(ControlData.pData++)); } printf(\"\\n\"); ControlData.wCount-=ControlData.wLength; if(ControlData.in == 1)sendcommand(0xf1); sendcommand(0xfa); if(bEPPflags.bits.read) { ControlData.wLength=64; ControlData.wCount=64; ControlData.pData=&Databuf[bEPPflags.bits.LogicalBlockAddress]; bEPPflags.bits.LogicalBlockAddress+=64; bEPPflags.bits.TransferLength--; if(!bEPPflags.bits.TransferLength){ bEPPflags.bits.outhead=1; bEPPflags.bits.read=0; } }else if(bEPPflags.bits.outhead && !ControlData.wCount) { ControlData.wLength = 13; ControlData.wCount = 13; ControlData.pData = (char*)&CSWsection.Head[0]; bEPPflags.bits.outhead=0; } } void CBW_Read10(void){ bEPPflags.bits.LogicalBlockAddress=SWAP32(CbwCommandBuf.OperationData.CommandCode.read10.LogicalBlockAddress)*512; bEPPflags.bits.TransferLength=((unsigned long)SWAP16(CbwCommandBuf.OperationData.CommandCode.read10.TransferLength))*512; bEPPflags.bits.read=1; CreateCSWsection(); if(bEPPflags.bits.TransferLength){ ControlData.wLength=64; ControlData.wCount=64; ControlData.pData=&Databuf[bEPPflags.bits.LogicalBlockAddress]; bEPPflags.bits.LogicalBlockAddress+=64; bEPPflags.bits.TransferLength--; if(!bEPPflags.bits.TransferLength){ bEPPflags.bits.outhead=1; bEPPflags.bits.read=0; } } else{ ControlData.wLength=0; ControlData.wCount=0; bEPPflags.bits.outhead=1; bEPPflags.bits.read=0; } USB_submit(); } 6 DO 55 53 42 43 -
