Windows reports a faulty device driver or corrupted controller. Solutions: Fixing VID 1E3D PID 198A Drives
: You will find this ID in many unbranded or "white-label" USB drives, including those from brands like Lenovo (OEM) or promotional "free" thumb drives.
If you have opened your Windows Device Manager, Linux lsusb output, or a USB diagnostic tool and stumbled upon the cryptic string you are likely dealing with an unrecognized, malfunctioning, or driverless piece of hardware. Usb Device Id Vid 1e3d Pid 198a
: Likely ChipsBank CBM2199S or a similar CBM-series chip Interface : USB 2.0 (High Speed)
| | 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. | Windows reports a faulty device driver or corrupted
To find out exactly what microchip and flash memory are sitting inside your device without physically cracking open the casing, use a specialized hardware diagnostics tool.
This ID usually represents a ChipsBank-based Flash Disk or Flash Drive. : Likely ChipsBank CBM2199S or a similar CBM-series
represents a specific mass storage device powered by a ChipsBank Microelectronics microcontroller , most commonly identified as the CBM2098, CBM2199A, or CBM2199E . This hardware fingerprint belongs to budget-tier USB flash drives, promotional corporate "swag" drives, or unbranded flash disks manufactured in bulk.

The combination of VID: 1e3d and PID: 198a uniquely identifies a USB device.
Every USB device uses a unique identifier consisting of a Vendor ID (VID) and a Product ID (PID). These markers tell the operating system what drivers to load and how to interact with the underlying hardware.
