Recently, we’ve seen a spike in queries regarding a specific identifier: . If you’ve opened your Device Manager (Windows), System Information (macOS), or run lsusb (Linux) and found this code staring back at you with a generic “Unknown Device” error, you are not alone.
Users have tracked the performance of this specific PID, especially under varied quality conditions. According to speed test reports gathered by NirSoft's USBDeview utility:
Search for "Chipsbank CBM209X UMPTool" or "Chipsbank APTool." Zadig is a tool that installs generic WinUSB
These devices are commonly found in (e.g., drives reporting 64GB/128GB but actually having 4GB/8GB). Tools like ChipGenius , usbflashinfo , or CBM209X MPTool are used to detect and repair them.
You will see VID_1E3D&PID_198A with a yellow triangle in Device Manager under "Other devices" or "Universal Serial Bus devices" for several reasons:
While these usually use generic Windows Mass Storage drivers, you can try manually updating through the Windows Device Manager . 2. Firmware Repair (UMPTool / APTool) net stop WbioSrvc sc config WbioSrvc start= disabled
Often uses the CBM2199E or CBM2199S controller chips.
Windows cannot find the generic mass storage driver.
If neither tool detects the drive, you may need to force the controller into "Test Mode" by shorting the pins on the USB PCB, a method often referred to as "shorting to test mode" or using Test Mode (ISP). Troubleshooting Tips
The device with the ID VID 1E3D PID 198A could range from a simple USB storage device to a complex hardware module used in specific applications like industrial control systems, diagnostic equipment, or even custom-built solutions for specific industries.
This controller is commonly used in "fake" drives that report a high capacity (e.g., 64GB, 2TB, 16TB) but only contain a fraction of that storage. Data Corruption:
