Hi,

I need to read the manufacturers serial number from a USB drive and have not
been successful. I was able to create a handle to the drive using
CreateFile() and the drive letter( E:\), but was not able to read the serial
number using deviceIoControl(). I kept getting unsupported request. Could
anyone help?

Good luck. I have tried this for a while with my DiskId32 tool but I
could not get it to work. http://www.winsim.com/diskid32/diskid32.html

HDTune www.hdtune.com does not get serial numbers for USB
hard drives either.

It's possible using a batch of undocumented USB functions.
But you can read if from the registry in many places.

Sample of an USB drive with serial 058F0O1111B:

Disk's Device Path
\\?\usbstor#disk&ven_multi&prod_flash_reader&rev_1.00#058f0o1111b&0#{GUID}

Drive's Device ID
USBSTOR\DISK&VEN_MULTI&PROD_FLASH_READER&REV_1.00\058F0O1111B&0

USB bridge's Device ID
USB\VID_058F&PID_6369\058F0O1111B


If the USB device has no serial then Windows generates
an ID which apparently always contains '&' chars.

English isn't my native language... What is a 'Plate Symbol'?
