Some devices allow reflashing the EEPROM using tools like ftdi_eeprom (for FTDI clones) or ch34x_eeprom to set a correct VID, making the device safer and more compatible.

The controller chip (often made by manufacturers such as FirstChip, Alcor, or Phison) may develop a physical fault. In some documented cases, even brand‑new drives from low‑cost brands have failed in this way. For example, a 32 GB Good Ram USB drive was found to have a FirstChip FC1178BC controller that stopped responding and reported VID FFFF PID 1201 . The controller chip (often made by manufacturers such
We voted—by gesture, not voice. The device’s fate would be decided not by law but by story. If enough people believed a story of destruction, perhaps the device’s myth would die and the ledger’s power with it. If enough people believed a story of stewardship, perhaps it would become a shared archive for the lonely.
To understand the significance of ffff:1201 , it's helpful to first know what VID and PID represent. Every USB device contains a unique identifier known as the Device ID. This ID is comprised of two main parts: the , assigned by the USB-IF to specific manufacturers, and the Product ID (PID) , assigned by the manufacturer to a specific product model. For all USB devices, the Windows bus driver reports a device ID in the format USB\VID_xxxx&PID_yyyy , where xxxx and yyyy are taken directly from the idVendor and idProduct fields of the device descriptor.
