How do I mapping usb storage device path to physicaldrive?
I get the usb device path from
SetupDiGetDeviceInterfaceDetail()
and I can get the device path such like
\?usbstor#disk&ven_&prod_2307_pram&......
but I want to map device path to physical drvie
-> \physicaldrive0,1,2......
or inverse I can map physical drvie to device path
Is there any way to do that?

oh, I found it.
put the HANDLE into DeviceIoControl and use IOCTL_STORAGE_GET_DEVICE_NUMBER
STORAGE_DEVICE_NUMBER number; //use this to get disk numbers
DWORD readed; // discard results
BOOL result = DeviceIoControl(
hdl, // handle to device
IOCTL_STORAGE_GET_DEVICE_NUMBER, // dwIoControlCode
NULL, // lpInBuffer
0, // nInBufferSize
&number, // output buffer
sizeof(number), // size of output buffer
&readed, // number of bytes returned
NULL // OVERLAPPED structure
);
and the number.DeviceNumber is the PhysicalDrive number
