The USB Device ID VID 0951 PID 1666 refers to a specific hardware identifier for several popular Kingston Technology flash drives, most notably the DataTraveler 100 G3, DataTraveler G4, SE9 G2, and the 50 Kyson.
These identifiers are used by your operating system to recognize the manufacturer (VID) and the specific model (PID) to load the correct drivers. Identifying Your Device The ID breakdown is as follows:
VID (Vendor ID) 0951: Officially assigned to Kingston Technology.
PID (Product ID) 1666: Refers to a range of Kingston USB 3.0/3.1 Gen 1 mass storage devices.
You can verify these IDs on your own system by following these steps: Open Device Manager on your PC. Expand the Universal Serial Bus controllers section. Right-click your USB device and select Properties.
Under the Details tab, select Hardware Ids from the dropdown menu to see the VID_0951&PID_1666 string. Common Internal Hardware
While the external model might be a "DataTraveler 100 G3," the internal components can vary. Common configurations for this ID include: Controller: Often uses the Phison PS2251-19 or PS2251-07. usb device id vid 0951 pid 1666 link
Flash Memory: Frequently features Toshiba TLC or similar NAND flash chips.
Performance: These drives typically support "Super Speed" (USB 3.x) with sequential read speeds often tested between 80-130 MB/s, though write speeds are significantly lower. flash drive becomes write-protected after failed sync
The popularity of the DataTraveler 100 G3 makes it a target for counterfeiters. Fake drives often report false capacities (e.g., claiming to be 1TB when they are only 32GB).
If you are verifying a drive using the VID/PID, be aware that sophisticated fake drives often clone the VID and PID of the genuine article. If the VID/PID matches but the drive performs incredibly slowly or corrupts data, you may have a counterfeit device. Always test the actual capacity and read/write speeds against the official Kingston specs.
You mentioned the word "link." There are two likely reasons why you are researching this specific PID:
This specific model is a popular target for counterfeiters. If you bought this drive from a third-party marketplace (not a major retailer) and the storage capacity seems suspicious (e.g., showing as 1TB for a very low price) or files are disappearing after writing, you may have a fake drive. Tools like H2testw can verify the true capacity of the flash memory. The USB Device ID VID 0951 PID 1666
Summary: The VID 0951 PID 1666 device is the reliable, budget-friendly Kingston DataTraveler 100 G3. If it isn't working, try reinstalling the driver in Device Manager or switching USB ports.

Imagine this: You plug a USB drive into your computer. It doesn’t show up. Or maybe it shows up as an “Unknown Device” with a yellow exclamation mark. You dive into the Device Manager, navigate to the hardware IDs, and see a cryptic string: USB\VID_0951&PID_1666.
What does this code mean? Is your device broken? Do you need a special driver? And what about that "link" everyone talks about?
This article decodes the mystery of USB\VID_0951&PID_1666. We will explain what these numbers signify, which specific product they represent, why the “link” is critical for drivers and support, and how to solve common problems related to this device.
No link required. Linux uses the usb-storage module. macOS uses native mass storage support. If not mounting, check Disk Utility.
Solution: Check lsusb – you should see Bus XXX Device XXX: ID 0951:1666 Kingston Technology. If seen but not mounted, run:
sudo dmesg | grep -i usb
sudo mount /dev/sdb1 /mnt/usb (adjust device name accordingly)
