Usb Device Id Vid Ffff Pid 1201 [2021] -

FirstChip FC1178BC MpTools V1.0.2.10 2018-04 ... - USBDev.ru

A 16-bit number assigned by the USB Implementers Forum (USB-IF) to specific companies.

Because PID 1201 is strictly associated with FirstChip microcontrollers, standard formatting tools like Rufus or Windows Disk Management will fail. You must use the factory mass-production software.

When Windows or Linux reads VID_FFFF&PID_1201 , it is interacting with a baseline microcontroller running raw, factory-level code rather than a finalized consumer product firmware. Common Symptoms of This Hardware ID usb device id vid ffff pid 1201

+-----------------------------------------------------------------------+ | USB DEVICE DESCRIPTOR | +-----------------------------------------------------------------------+ | Hardware String: USB\VID_FFFF&PID_1201 | | Vendor ID (VID): 0xFFFF (Placeholder / Non-USB-IF Registered OEM) | | Product ID (PID): 0x1201 (NAND USB2DISK / Disk 2.0) | | Protocol Class: Mass Storage Device (USB 2.0 High Speed) | | Core Controller: FirstChip FC1178BC / chipYC2019 | +-----------------------------------------------------------------------+

Treat the device as a technical engineering tool. If this device appeared unexpectedly in a corporate environment, it should be treated with suspicion as it does not conform to standard hardware compliance profiles.

Linux tools like lsusb detect the hardware identifier ID ffff:1201 , but fdisk -l cannot communicate with it. FirstChip FC1178BC MpTools V1

Hold the button down while plugging the device into your PC to force it into a clean programming state.

Open Windows to verify the storage capacity. Fake or low-tier counterfeit drives originally labeled as "64GB" or "128GB" often shrink down to their real physical sizes, such as 16GB or 32GB , after a raw factory scan. The factory tool locks out defective or missing memory sectors to stabilize the drive. This ensures that any remaining storage space is safe to use without causing future file corruption. If you run into issues during the repair process, tell me:

Abruptly pulling out the drive during a read/write operation can cause the controller to lose its configuration. How to Fix USB VID FFFF PID 1201 You must use the factory mass-production software

The drive is communicating, but it has no "instructions" on how to manage the memory storage.

If the drive is inaccessible, the following steps are typically recommended by tech communities:

This indicates that the drive is being detected but cannot be initialised as a storage device.
