Id like to use USB Flash Drive as some sort of key that protects my software from unauthorized use. That is the software will only run if flash drive I issue to the user is inserted into any USB port on the PC.
 
Is there any BIOS or firmware unique ID or date/time on any typical flash drive and which API can I use to read those?
 
Thank you.

Hi mvoronkin
The following link retrieves the hardcoded sn of the usb flash drive:

The limitation of using sn of a flash drive is that not all usb flash drives have sn.
