Content Security Features in Usbccgp.sys
Digital Rights Management (DRM) systems often make use of device serial numbers to ensure that legitimate customers have access to digitized intellectual property. If a USB device has a CSM-1 content security interface, a client driver can query for its serial number by sending an IOCTL_STORAGE_GET_MEDIA_SERIAL_NUMBER request to the generic parent driver.
