USB flash drive / storage device (often used in unbranded or OEM USB sticks)
Every USB device uses a Vendor ID (VID) and Product ID (PID) assigned by the USB Implementers Forum (USB-IF) to tell the host operating system what drivers to load. ID Component Hexadecimal Code Identified Entity 1E3D Chipsbank Microelectronics Co., Ltd. Product ID (PID) 198A Mass Storage Flash Disk Architecture Common Microcontrollers ChipsBank CBM2098, CBM2199A, CBM2199E Protocol Interface USB 2.0 High Speed (Max 100mA current draw) Common Symptoms of Controller Corruption
If this device appears as an "Unknown Device" in Windows Device Manager:
usb 3-2: New USB device found, idVendor=1e3d, idProduct=198a, bcdDevice= 1.00 usb 3-2: Product: CBM2099 usb 3-2: Manufacturer: Chipsbank Usb Device Id Vid 1e3d Pid 198a
The USB device ID identifies a Chipsbank CBM2099 series flash drive controller. While driver issues, firmware corruption, and counterfeit hardware are common, most problems are solvable using Windows Device Manager, the official Chipsbank MP Tool, or Linux command-line utilities. Always test cheap flash drives for fake capacity, and never store irreplaceable data on a single USB drive – regardless of its VID/PID.
Understanding the USB Device ID VID 1e3d PID 198a: Troubleshooting and Drivers
This combination typically points to a mass storage device utilizing the or USB flash drive / storage device (often used
The drive drops its FAT32/NTFS partition mapping table and defaults into an inaccessible RAW format state .
: In tech circles, Chipsbank devices are sometimes associated with "fake capacity" drives—cheap sticks programmed to report more storage than they actually have—though this ID is also used for many legitimate, small-capacity budget drives. How to Check It
Once your data exceeds the true physical capacity (e.g., past 16GB), the controller continuously overwrites older data, permanently corrupting your files. How to Verify the True Specifications of Your Device : In tech circles, Chipsbank devices are sometimes
The USB device identifier VID_1E3D PID_198A refers to a specific piece of hardware commonly found in automotive diagnostic and telematics applications.
To mount or repair:
: To fix firmware-related issues or "No Media" errors, specialized mass production tools (MPTools) like specifically for Chipsbank controllers are often required. Performance Data Benchmarks from NirSoft's USB Speed Tests indicate varying real-world performance for this VID/PID: Write Speeds : Generally low, ranging from ~3 MB/s to ~10 MB/s. Read Speeds : Typically around 15 MB/s to 25 MB/s.
