Try shifting the drive to a rear motherboard USB port. If it still fails to read, the device may need to be put into "Test Mode" by manually shorting specific pins on the controller circuit board. 💾 Firmware & Recovery Tools

While VID 1e3d indicates the chip, the brand name on the outside of the casing could be many different companies. To know exactly what you are plugging in, you can check Device Manager: the Start button and select Device Manager . Expand Universal Serial Bus controllers .

When you connect a USB device to a computer, the operating system uses the VID and PID to identify the device and install the appropriate driver.

| Parameter | Value / Range | | ------------------------ | ------------------------------------------- | | | 2.0 Full Speed (12 Mbps) | | Max Packet Size (EP0) | 64 bytes | | Number of Configurations | 1 | | Number of Interfaces | 1 to 2 (e.g., DFU + optional vendor-specific) | | Power Consumption | <100 mA (bus-powered) | | Supported OS | Windows (with custom driver), Linux (libusb), macOS (via libusb) |

No. It is a legitimate hardware identifier. However, some malware modifies USB descriptors. If the device behaves erratically (opens folders automatically), scan with Windows Defender or Malwarebytes.

[USB Host Connection] ---> [Chipsbank Controller (e.g., CBM2199E)] ---> [NAND Flash Memory (TLC/MLC)]

If you need to recover data (not just make the drive work), do not run the MP Tool. Instead, use (Windows) or lsusb -v (Linux) to query deeper parameters:

You might encounter VID_1E3D&PID_198A for several reasons. Here are the most common scenarios:

Type list disk to locate your drive number (match it by size).

The device likely requires specific drivers and software to function properly. The driver and software support might be available from the manufacturer's website or through a third-party repository.

. This specific hardware signature is most commonly associated with generic flash drives, USB sticks, and some counterfeit storage media. Device Specifications Vendor ID (VID): (Chipsbank Microelectronics Co., Ltd.). Product ID (PID): (Flash Disk / USB Mass Storage Device). Controller Part-Number: Often uses the controller. Typically USB 2.0 (High Speed). Power Consumption: Standard maximum current of 100mA. Common Use Cases and Issues
