Re:誰知道禁用USB端口的函數(shù)啊！？！ 是不是要自己寫方法哦！
我做了個MP3的量產(chǎn)軟件，當對MP3的文件download完成后會將MP3安全移除。
問題是：我用GUID{0xA5DCBF10L, 0x6530, 0x11D2, 0x90, 0x1F, 0x00, 0xC0, 0x4F, 0xB9, 0x51, 0xED}會將USB鍵盤和USB鼠標全都枚舉出來，這樣我就無法區(qū)分誰是MP3，誰是USB鍵盤和鼠標了。雖然枚舉時我可以得到PID和VID，但是我們的PID和VID可能會被代理商更改，所以也就不能通過PID和VID來區(qū)分了，不知PC上的安全刪除U盤是怎樣做到的，PC應(yīng)該可以將盤符和對應(yīng)的設(shè)備對應(yīng)起來，且能用唯一的標識來區(qū)分每臺設(shè)備，情況緊急，求求各位高手拉我一把吧，非常感謝！

我的代碼如下：
void CLogicDriveList::RemoveDevice(size_t index)
{
char szDevDesc[256] = {0};
HDEVINFO hDevInfo;
string Prod;
string Rev;

//遍歷所有的設(shè)備
hDevInfo = SetupDiGetClassDevs((LPGUID)&GUID_CLASS_USB_DEVICE, NULL, NULL, DIGCF_PRESENT|DIGCF_DEVICEINTERFACE) if ( INVALID_HANDLE_VALUE == hDevInfo)return;

SP_DEVINFO_DATA devInfoData;
devInfoData.cbSize = sizeof(devInfoData);

int Index = 0;
while(SetupDiEnumDeviceInfo(hDevInfo, Index++, &devInfoData))
{
//獲取設(shè)備ID
std::string devId;
memset(szDevDesc, 0, sizeof(szDevDesc));
devInfoData.cbSize = sizeof(devInfoData);

CM_Get_Device_ID(devInfoData.DevInst, szDevDesc, sizeof(szDevDesc),0);
devId = szDevDesc;
cout<<devId<<endl;
//比較設(shè)備ID
if(這里該怎樣填呢？)
{
if(EjectDevice(devInfoData))
{
cout<<"Remove device "<<m_LogicDrives [index].Symbol<<": ok"<<endl;
break;
}
else
cout<<"Remove device "<<m_LogicDrives[index].Symbol<<": fail"<<endl;
}
}
}

bool CLogicDriveList::EjectDevice(const SP_DEVINFO_DATA &devInfoData)
{
PNP_VETO_TYPE   pnpvietotype;  
char vetoname[MAX_PATH] = {0};  
CONFIGRET cr = CM_Request_Device_Eject(devInfoData.DevInst,  
                        &pnpvietotype,
vetoname,
MAX_PATH,
0);  
return CR_SUCCESS==cr;
}
