From a practical standpoint, when a system enumerates a “13fe usb disk 50x usb device,” the OS loads the standard usbstor.sys (Windows) or usb-storage (Linux) driver. The device then appears as a logical unit (e.g., /dev/sdb in Linux or E: in Windows). No special drivers are needed because the mass storage class is universally supported — a deliberate design choice that made USB flash drives so successful.
For digital forensics, the identifier 13fe:50x is valuable but not absolute. While the VID/PID can be used to filter devices in USB device history logs (e.g., Windows SetupAPI.dev.log or Linux dmesg ), advanced malware or anti-forensics tools can reprogram these identifiers. A malicious USB Rubber Ducky or BadUSB device might masquerade as 13fe to avoid suspicion. Conversely, a legitimate Kingston drive with a corrupted firmware might show a garbled or different VID/PID, leading to misidentification. 13fe usb disk 50x usb device
