Serial number on usb flash drive.

NTDEV

I am unable to get the serial number on usb flash drives. It always returns
0 indicating it is not there. I am using DeviceIoControl with
IOCTL_GET_DEVICE_DESCRIPTOR to get the venderID, productID, and
ProductRevision, but the SerialNumber is always 0.

Has anyone run into a similar problem?

Regards,
Gautam

If you are trying to get the usb disk serial number your best bet is to use
scsi passthrough to send an inquiry request for inq page 80.

This exact question, with the exact same wording and the exact same
spelling errors, was posted to one of the newsgroups in September,
2005. Did you just cut-and-paste the entire question here? Were you
not satisfied with Maxim’s answer?
