hi,
i need to get the serial number of the usb drive? any interrupt or what to do to get the serial number of the usb????


Thanks in advance.

I don't think the BIOS has any interrupts for dealing with USB specifically, you will most likely need to access the USB Hubs and the device manually and ask it for the serial manually.

what you're looking for lays in USB device descriptors (see clicker code), and should hopefully be the "serial" field.

See http://www.osdev.org/osfaq2/index.php/USB%20Tutorial for a clue on how those descriptors can be retrieved ... but we still have plenty of work to do about this ...
