VID:1E3D PID:198A is a generic USB identifier for Chipsea Technologies microcontrollers operating in bootloader or vendor-specific bridge mode. It is not a consumer product but a development or OEM interface. Correct operation requires custom drivers and is typically seen by engineers flashing firmware or reading sensor data from a Chipsea-based device.
If you encounter this device and are not developing embedded hardware, it is likely part of a commercial product (e.g., smart scale, USB fan controller, or soldering iron) that uses a Chipsea MCU internally.
The USB device with VID 1e3d and PID 198a is a generic Flash Disk powered by a Chipsbank Microelectronics controller. These components are frequently found in unbranded or "OEM" USB flash drives, as well as some budget-branded products like those from Lenovo. Quick Verdict
This device is typically a budget-tier USB 2.0 drive. While functional for basic file transfers, it is not recommended for high-performance needs or critical data backups. It is also a common hardware profile for "fake capacity" drives sold on discount marketplaces. Key Specifications & Features Manufacturer: Chipsbank Microelectronics Co., Ltd. Usb Device Id Vid 1e3d Pid 198a
Controller: Likely ChipsBank CBM2199S or a similar CBM-series chip Interface: USB 2.0 (High Speed)
Reported Capacities: Varies widely from 8GB to "16TB" (though large capacities are often spoofed) Power Consumption: Max 100mA Review Analysis
Performance: Users generally report standard USB 2.0 speeds, which are slow by modern standards. Expect read/write speeds significantly lower than USB 3.0 or 3.1 drives. VID:1E3D PID:198A is a generic USB identifier for
Reliability: Community reports from sites like USBDev.ru and Elektroda suggest these drives are prone to "no medium" errors or data corruption over time.
Authenticity Warning: This specific VID/PID combination is heavily associated with scam drives (e.g., "16TB" drives from AliExpress). The controller is often programmed to report a much higher capacity to the OS than the physical NAND flash actually has. Expert Recommendation
If you already own this device, use a tool like H2testw or FakeFlashTest to verify its actual capacity before trusting it with important files. If you are looking to purchase a reliable drive, consider established brands like Kingston or SanDisk. To mount or repair:

To mount or repair:
For low-level access, use sudo ./cbmtool (open-source utility for Chipsbank controllers, available on GitHub).
The identifiers "VID 1E3D" and "PID 198A" are USB Vendor ID (VID) and Product ID (PID) values used by an operating system to recognize a specific USB device. Together they uniquely identify the manufacturer (VID) and the product model (PID) so the OS can load the correct driver or take an appropriate action.
