NamingSystem USB VID and PID as a device identifier - FHIR specification

The USB identifiers VID 0951 and PID 1666 correspond to the Kingston Technology DataTraveler series of flash drives. This specific combination is widely used across several mainstream Kingston USB 3.0 and 3.1 models, most notably the DataTraveler 100 G3. Device Identification Vendor ID (VID) 0951: Registered to Kingston Technology.

Product ID (PID) 1666: Associated with the DataTraveler product line, including the 100 G3, G4, SE9 G2, 50, and Kyson models. usb device id vid 0951 pid 1666 link

Internal Hardware: These drives frequently utilize Phison controllers (such as the PS2251-07 or PS2251-09) and Toshiba or Micron flash memory. Performance and Specifications

Interface: USB 3.0/3.1 Gen 1 (backwards compatible with USB 2.0).

Speeds: Typical read speeds for these models range from 40 MB/s to 140 MB/s, while write speeds are generally lower, often between 10 MB/s and 60 MB/s depending on the specific capacity and host port. Capacities: Available in sizes ranging from 16GB to 256GB. Common Issues and Troubleshooting

If your computer displays this VID/PID but the drive is not working (e.g., "Device Not Recognized" or shows "0MB" capacity), it often indicates a controller or firmware failure. VID = 951 (Kingston Technology), PID = 1666

VID 0951 PID 1666 in Different Operating Systems

| OS | Recognition | Needed Driver | Link | |----|-------------|---------------|------| | Windows 10/11 | Automatic | USBSTOR.SYS | Built-in | | Windows 7/8 | Automatic | USBSTOR.SYS | Built-in | | Linux (all distros) | Automatic via usb-storage | Kernel module | None needed | | macOS (all versions) | Automatic | IOUSBMassStorageClass | None needed | | ChromeOS | Automatic | – | None needed |

If your OS is not recognizing it despite these, the issue is likely hardware (failing USB port, broken drive, or damaged connector).

Problem 4: Linux not mounting the drive

Solution: Check lsusb – you should see Bus XXX Device XXX: ID 0951:1666 Kingston Technology. If seen but not mounted, run: The USB identifiers correspond to various flash drives

sudo dmesg | grep -i usb
sudo mount /dev/sdb1 /mnt/usb (adjust device name accordingly)

Problem 1: "Unknown USB Device (Device Descriptor Request Failed)"

Error code: 43 in Device Manager.

Why? This is the #1 complaint for the DT100 G2. It does not mean the driver is missing. It means the USB controller could not communicate with the device.

Solutions:

  1. Test another port: Use a USB 2.0 port directly on the motherboard (back of PC). Avoid USB hubs and front-panel ports.
  2. Test another computer: If it fails on all ports and all PCs, the drive’s internal hardware or controller chip has failed. VID 0951 PID 1666 will remain visible but the drive is likely dead.
  3. Uninstall the device: Right-click the unknown device → Uninstall. Then unplug, reboot, and replug.

Part 6: Is Kingston Still Supporting the DT100 G2 (VID 0951 PID 1666)?

The DataTraveler 100 G2 was discontinued years ago. It was an entry-level drive from the early 2010s. However, Kingston’s support for legacy products remains active.

What you will not find:

  • A dedicated driver download package.
  • Windows 11-specific drivers (the generic ones work).
  • A "link" to a magical .exe that fixes everything.

What you will find:

  • Warranty support (all Kingston drives have 5-year or lifetime warranty depending on region).
  • Technical advice via email/chat.
  • Kingston Format Utility (still works for this VID/PID).

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). Problem 4: Linux not mounting the drive Solution:

1. The Translation: What is VID 0951 PID 1666?

Every USB device contains a unique identifier programmed by the manufacturer.

  • VID 0951: This Vendor ID belongs to Kingston Technology, the American multinational computer technology corporation famous for its memory products.
  • PID 1666: This Product ID refers specifically to the Kingston DataTraveler 100 G3 (DT100G3).

Therefore, if your computer is detecting a device with these IDs, you are using a Kingston DataTraveler 100 Generation 3 USB 3.0 Flash Drive.

1. The "Driver Link" (Windows Update Error)

Many users search for this ID when Windows fails to install the driver automatically. You might see a yellow exclamation mark in Device Manager.

  • The fix: This device uses Microsoft’s generic USB mass storage driver. Uninstall the device from Device Manager, unplug it, reboot, and plug it back in. Do not download "driver updater" tools—Kingston does not provide custom drivers for this model.

4. Linux / macOS

No link required. Linux uses the usb-storage module. macOS uses native mass storage support. If not mounting, check Disk Utility.

The "Link" in Your Search – What Are You Really Looking For?

The keyword includes the word "link", which likely refers to one of these:

  1. Driver download link – to make the device work again.
  2. Official support link – from Kingston or Microsoft.
  3. Manual installation link – within Windows Device Manager.
  4. Firmware or format utility link – to restore the drive.
