Subject: how to get serial_no from usb HD disk (HDIO_GET_IDENTITY ioctl, hdparm -i)

How can I get serial_no from usb-attached HD drive ?

 The HDIO_GET_IDENTITY ioctl fails (like 'hdparm -i').
 Any advice on how to extract the drive serialNo from the usb disk ?
 Can I write kernel module to extract the SerialNo ?
 (I don't need whole 'struct hd_driveid', only the SerialNo).

 Thanks
 Yakov
