Usb Device Id Vid 0951 Pid | 1666 _verified_
The USB Hardware ID VID 0951 PID 1666 identifies a Kingston DataTraveler 3.0 series flash drive
This error usually means the computer can talk to the USB controller chip, but the controller cannot communicate with the physical NAND flash memory blocks.

Run the specific MPTool to overwrite the drive's corrupted microcode.
If your computer identifies the device as an "Unknown USB Device" or "Device Descriptor Request Failed" with this ID, try these steps: flash drive becomes write-protected after failed sync
In some cases, an incorrectly performed firmware update (often called "flashing" or "mass production") can "brick" the drive, rendering it completely unusable. The 0951:1666 has been widely discussed in the context of failed "mass production" attempts. The common consensus in technical forums is that drives with a are particularly difficult to recover from a bricked state. In many of these advanced failure scenarios, the only reliable solution is to use the product's warranty. The USB Hardware ID VID 0951 PID 1666
If your drive has completely failed physically, you may need to check the NirSoft speed tests to verify if the performance (20-30 MB/s) matches your experience.

Use a tool like Flash Drive Information Extractor to confirm the specific Phison controller (e.g., PS2251-07 or PS2319).
Confirm via ChipGenius that your controller is a Phison PS2251-07 or similar.
