| | Symptom | Likely Cause | Solutions | | :--- | :--- | :--- | :--- | | Driver Not Found / Unknown Device | Device Manager shows a yellow exclamation mark. | Standard Windows driver conflict or missing driver. | 1. Right-click start button and select "Device Manager". 2. Find unknown device, right-click, and select "Update driver". 3. Select "Search automatically for drivers". If that fails, click "Browse my computer for drivers" and navigate to C:\Windows\System32\DriverStore\FileRepository . | | Detected but 0 Bytes | Drive appears in File Explorer with a drive letter but shows 0 bytes used/free. | Firmware or partition corruption, often from improper ejection. | Chance of Data Recovery : Low, but possible with DMDE. Main Solution (Low-Level Repair) : Use CBM UMPTool or APTool . Follow the "Using UMPTool & APTool: The Fix" section. | | Fake Capacity | OS reports 64GB, but fails to write data beyond ~4GB. | This is a fake "capacity-expanded" drive. | 1. Test with H2testw : Write and verify full capacity. 2. Fix with UMPTool : After identifying true capacity, use UMPTool to re-flash firmware with correct parameters. | | Linux/macOS Detection | Not mounted or found in lsblk , but visible in lsusb / dmesg . | Often a driver or power management conflict. | 1. Check sudo dmesg -w when plugging in. 2. Try different USB port (preferably USB 2.0). 3. Install/update usbutils package. | | Bootable USB Failure | Cannot boot or write image with Rufus/BalenaEtcher. | BIOS boot sector corruption or configuration error. | 1. Use Rufus : With drive inserted, run Rufus, select drive, and click "START". 2. Low-level repair : If Rufus fails, use UMPTool. Erase the entire device, re-flash, then recreate bootable media. | Usb Device Id Vid 1e3d Pid 198a
When these generic drives experience firmware corruption, file-system degradation, or partition failure, they often display errors such as This detailed guide covers what this hardware ID means, why it encounters technical issues, and how to entirely restore its functionality using specialized flashing utilities. Decoding the Hardware Identifier: VID 1E3D & PID 198A
This designates the specific product line or firmware profile used by the controller.
This identifier does not correspond to mainstream consumer gadgets like a standard mouse, keyboard, or flash drive. Instead, it points to a specific, specialized chipset. In this 2,500-word deep dive, we will uncover exactly what device uses this ID, why it may not be working, how to fix driver errors, and advanced troubleshooting steps for Windows, Linux, and macOS. VID:1E3D PID:198A is a
Type create partition primary followed by format fs=exfat quick . 3. Low-Level Firmware Flashing (Mass Production Tools)
Because this drive is based on a ChipsBank controller, generic Windows formatting tools often fail. You need specialized ChipsBank controller tools. Method 1: Using ChipsBank APTool (Flash Utility) This is the most effective way to repair these drives.
Yes, frequently. The Chipsbank CBM2099 controller is often used in . Scammers program the controller to report a fake capacity – for example, a 64GB drive may actually contain a 4GB NAND chip with a looped-overwrite firmware. | Attribute | Details | | ------------------ |
198A (Commonly assigned to Flash Disks and Flash Readers) Device Type: USB 2.0 Mass Storage Device Common Controllers: CBM2098, CBM2099E, CBM2199S 🛠️ Common Use Cases & Behavior
This ID usually represents a ChipsBank-based Flash Disk or Flash Drive.
If your computer cannot properly identify or communicate with this device, it is almost certainly a driver issue or a failure of the device’s internal controller. 1. Reinstall the USB Driver (Easiest Solution)
Before diving into the specifics of 1E3D and 198A , let’s break down the terminology. Every USB device plugged into your computer contains two unique identifiers burned into its firmware:
For the most serious issues, only software used at the factory will work. This is where the comprehensive information from the VID/PID becomes invaluable, as it tells you which tool is compatible. These powerful tools, commonly referred to as "量产工具" (mass production tools), can perform low-level formatting and re-flash the controller's firmware.
