Retrieve serial number from USB memory (Windows environment c++) - c++

Question

I would need to retrieve the serial number from my USB memory, namely the hard disk's serial number that the manufacturer assigns. For this reason I cannot use GetVolumeInformation() as suggested in some other threads. I would need to have the "unique" number
I kindly ask you if you can share an example in C++ and Windows environment (Visual c++)
Thanks!

You can check out this article:- http://oroboro.com/usb-serial-number/
#include <WinIOCtl.h>
#include <api/usbioctl.h>
#include <Setupapi.h>
DEFINE_GUID( GUID_DEVINTERFACE_USB_DISK,
0x53f56307L, 0xb6bf, 0x11d0, 0x94, 0xf2,
0x00, 0xa0, 0xc9, 0x1e, 0xfb, 0x8b );
void getDeviceInfo( int vol )
{
UsbDeviceInfo info;
// get the device handle
char devicePath[7] = "\\\\.\\#:";
devicePath[4] = (char)( vol + 'A' );
HANDLE deviceHandle = CreateFile( devicePath, 0,
FILE_SHARE_READ |
FILE_SHARE_WRITE, NULL,
OPEN_EXISTING, 0, NULL );
if ( deviceHandle == INVALID_HANDLE_VALUE )
return;
// to get the device number
DWORD volumeDeviceNumber = getDeviceNumber( deviceHandle );
CloseHandle( deviceHandle );
// Get device interface info set handle
// for all devices attached to the system
HDEVINFO hDevInfo = SetupDiGetClassDevs(
&GUID_DEVINTERFACE_USB_DISK, NULL, NULL,
DIGCF_PRESENT | DIGCF_DEVICEINTERFACE );
if ( hDevInfo == INVALID_HANDLE_VALUE )
return;
// Get a context structure for the device interface
// of a device information set.
BYTE Buf[1024];
PSP_DEVICE_INTERFACE_DETAIL_DATA pspdidd =
(PSP_DEVICE_INTERFACE_DETAIL_DATA)Buf;
SP_DEVICE_INTERFACE_DATA spdid;
SP_DEVINFO_DATA spdd;
spdid.cbSize = sizeof( spdid );
DWORD dwIndex = 0;
while ( true )
{
if ( ! SetupDiEnumDeviceInterfaces( hDevInfo, NULL,
&GUID_DEVINTERFACE_USB_DISK,
dwIndex, &spdid ))
break;
DWORD dwSize = 0;
SetupDiGetDeviceInterfaceDetail( hDevInfo, &spdid, NULL,
0, &dwSize, NULL );
if (( dwSize != 0 ) && ( dwSize <= sizeof( Buf )))
{
pspdidd->cbSize = sizeof( *pspdidd ); // 5 Bytes!
ZeroMemory((PVOID)&spdd, sizeof(spdd));
spdd.cbSize = sizeof(spdd);
long res = SetupDiGetDeviceInterfaceDetail(
hDevInfo, &spdid, pspdidd,
dwSize, &dwSize, &spdd );
if ( res )
{
HANDLE hDrive = CreateFile( pspdidd->DevicePath,0,
FILE_SHARE_READ | FILE_SHARE_WRITE,
NULL, OPEN_EXISTING, 0, NULL );
if ( hDrive != INVALID_HANDLE_VALUE )
{
DWORD usbDeviceNumber = getDeviceNumber( hDrive );
if ( usbDeviceNumber == volumeDeviceNumber )
{
fprintf( "%s", pspdidd->DevicePath );
}
}
CloseHandle( hDrive );
}
}
dwIndex++;
}
SetupDiDestroyDeviceInfoList(hDevInfo);
return;
}
You get the device number by calling DeviceIOControl() with the handle to your device:
DWORD getDeviceNumber( HANDLE deviceHandle )
{
STORAGE_DEVICE_NUMBER sdn;
sdn.DeviceNumber = -1;
DWORD dwBytesReturned = 0;
if ( !DeviceIoControl( deviceHandle,
IOCTL_STORAGE_GET_DEVICE_NUMBER,
NULL, 0, &sdn, sizeof( sdn ),
&dwBytesReturned, NULL ) )
{
// handle error - like a bad handle.
return U32_MAX;
}
return sdn.DeviceNumber;
}
Next here is a method to recognize if a volume is removable media (e.g. like a usb or firewire disk):
bool isRemovableMedia( s32 vol )
{
char rootPath[5] = "#:\\";
rootPath[0] = (char)( vol + 'A' );
char szDosDeviceName[MAX_PATH];
char dosDevicePath[3] = "#:";
// get the drive type
UINT DriveType = GetDriveType( rootPath );
if ( DriveType != DRIVE_REMOVABLE )
return false;
dosDevicePath[0] = (char)( vol + 'A' );
QueryDosDevice( dosDevicePath, szDosDeviceName, MAX_PATH );
if ( strstr( szDosDeviceName,"\\Floppy") != NULL )
{
// its a floppy
return false;
}
return true;
}
