	const int index, 
	int& numDrives,
	char* drives, 
	int& drives_len, 
	char* serial,

Vendor specifications:
drives [out] 
Pointer to char that receives the list of drive letters associated to the device. The drive letters have SCSI
format ( \\.\H: ) and they are separated by the terminating null character (ASCII code 0). A double terminating
null character is the end of list. If this parameter is NULL, function returns EUPICDSM_ERROR_PARAM_LEN
and iDriversLen receives the minimum size for containing the entire list.

EUPICDSM_LINK int __stdcall EupicdsmGetFlashInfoW(
	const int index, 
	int& numDrives,
	BSTR* pDrives, 
	BSTR* pSerial);

Vendor specifications: 
pDrives [out] 
Pointer to wide character string that receives the list of drive letters associated to the device. The drive
letters have SCSI format ( \\.\H: ) and they are separated by the terminating null character (ASCII code 0). A
double terminating null character is the end of list.
