If your drive fails and is under warranty, Kingston will replace it—but the replacement will be a newer model (likely a DataTraveler Exodia, with a different PID).
Even with the correct device ID, problems arise. Below are the most frequent issues and their fixes. : Recognized by the kernel as a standard mass storage device
If the drive is "Read Only," the PID 1666 hardware may have locked itself to prevent data loss.
This USB ID is widely reported in Windows Device Manager under "Universal Serial Bus controllers" or "Disk drives" when the device is properly functioning. However, if the driver is missing or corrupted, Windows may show it under "Other devices" as "Unknown device" with the hardware ID USB\VID_0951&PID_1666 . This identifier consists of two numbers: If your
