The device info is embedded in the firmware. It is not possible to write an application program to change it (same as in a disk drive). the only way to change the vendor/product IDs is to write a big check to the Manufacturer of your particular device. Even then, they won't give you a firmware image .. they'll just sell you USB sticks with your desired branding. So unless you have a minimum of $10K for this project ... forget it.
