经过这些日子以来对usb模块使用的反复阅读，终于解决了与pc通信的问题，供想学习改芯片的人提供参考，程序很粗略，但对于入门应该有些许帮组。下面的程序都已修改
这是我修改后上位机程序，用MFC编写的：
//全局变量
CCyUSBDevice *USBDevice = new CCyUSBDevice();
CCyControlEndPoint *ept = USBDevice->ControlEndPt;
CCyInterruptEndPoint *IntOut =  USBDevice->InterruptOutEndPt;
CCyInterruptEndPoint *IntIn =  USBDevice->InterruptInEndPt;
int  epCnt = USBDevice->EndPointCount();

void CWirelessDlg::OnButtonCheck()  //按下“设备检测”的程序响应
{
// TODO: Add your control notification handler code here
SetDlgItemText(IDC_EDIT_RECV,"");
if(USBDevice->IsOpen())
{
  bool bBulk, bIn;
  int  blkInCnt = 0;
  int vID,pID;
  CString str,temp;
  str = "USB设备已经连接！";
  vID = USBDevice->VendorID;
  pID = USBDevice->ProductID;
  temp.Format("VendorID = 0x%x",vID);
  str = str + "\r\n";
  str = str + temp;
  temp.Format("ProductID = 0x%x",pID);
  str = str + "\r\n";
  str = str + temp;
  PCHAR dn = new CHAR[256];
  dn = USBDevice->DeviceName;
  temp.Format("设备名称：%s",dn);
  str = str + "\r\n";
  str = str + temp;
  SetDlgItemText(IDC_EDIT_RECV,str);
  temp.Format("%s",dn);
  SetDlgItemText(IDC_COMBO_SET,temp);

  for  (int  e=0;  e<epCnt; e++) {
bBulk = USBDevice->EndPoints[e]->Attributes  == 3;
bIn = USBDevice->EndPoints[e]->Address & 0x80;
  if (bBulk && bIn)
  {
MessageBox("检测到输入终端");
  }
  if (bBulk && !bIn)
  {
MessageBox("检测到输出终端");
  }
  }
}
else
{
  SetDlgItemText(IDC_EDIT_RECV,"USB设备连接失败！");
}
}
void CWirelessDlg::OnButtonRevclear()
{
// TODO: Add your control notification handler code here
SetDlgItemText(IDC_EDIT_RECV,"");
}
void CWirelessDlg::OnButtonMansend()  //按下“手动放松”的程序响应
{
// TODO: Add your control notification handler code here
  unsigned char buf[4];
  ZeroMemory(buf, 4);
  LONG buflen =  4;
  buf[0] = 0x05;
  buf[1] = 0xc0;
  buf[2] = 0x05;
  buf[3] = 0xc0;
  if(IntOut)
MessageBox("找到输出设备") ;
  if((IntOut->XferData(buf,buflen))==TRUE&&USBDevice->IsOpen())
MessageBox("传输成功");
  else
MessageBox("传输失败");
}
void CWirelessDlg::OnButtonRecv()       //按下“开始接收”的程序响应
{
// TODO: Add your control notification handler code here
CString temp;
unsigned char buf[6];
LONG buflen =  6;
if(IntIn->XferData(buf,buflen)==TRUE)
{
  temp.Format("传输数据：%s",buf);
  MessageBox(temp);    //检测收到的数据，并显示
}
}
固件程序如下：
