what is win USB ?

the code for reading the USB should be as followes:
::ReadSector( DWORD startinglogicalsector, int numberofsectors)
{
char* buffer = (char*)malloc (512*numberofsectors);
HANDLE hDevice ;
// win 2k code

DWORD bytesread;

// Creating a handle to drive a: using CreateFile () function ..
char _devicename[] = "\\\\.\\A:";
_devicename[4] = Drive_letter;
hDevice = CreateFileA( _devicename,
GENERIC_READ,
FILE_SHARE_READ | FILE_SHARE_WRITE,
NULL,
OPEN_EXISTING,
0,
NULL);

if (hDevice == INVALID_HANDLE_VALUE)
return NULL;

// Setting the pointer to point to the start of the sector we want to read ..
SetFilePointer (hDevice, (startinglogicalsector*512), NULL, FILE_BEGIN);

if (!ReadFile (hDevice, buffer, 512*numberofsectors, &bytesread, NULL) )
return NULL;

CloseHandle(hDevice);
return buffer;
}

here is a code for reading one sector of USB:
::ReadSector( DWORD startinglogicalsector, int numberofsectors)
{
char* buffer = (char*)malloc (512*numberofsectors);
HANDLE hDevice ;
// win 2k code
DWORD bytesread;

// Creating a handle to drive a: using CreateFile () function ..
char _devicename[] = "\\\\.\\A:";
_devicename[4] = Drive_letter;
hDevice = CreateFileA( _devicename,
GENERIC_READ,
FILE_SHARE_READ | FILE_SHARE_WRITE,
NULL,
OPEN_EXISTING,
0,
NULL);

if (hDevice == INVALID_HANDLE_VALUE)
return NULL;

// Setting the pointer to point to the start of the sector we want to
read ..
SetFilePointer (hDevice, (startinglogicalsector*512), NULL, FILE_BEGIN);

if (!ReadFile (hDevice, buffer, 512*numberofsectors, &bytesread, NULL) )
return NULL;

CloseHandle(hDevice);
return buffer;
}
this is the cod efor reading the code for writing should be the same .

This is code for reading one sector from a USB floppy drive. That's all it
is good for. The original poster was talking about a VERY different kind
of device.
