Appendix A — Minimal checklist to run immediately
Because this architecture relies on the USB 2.0 interface running through budget-friendly Chipsbank controllers, transfer speeds are modest. Real-world benchmarking records show a wide variation based on the exact NAND flash chip inside: Low-End Range High-End Range ~10.33 MB/Sec ~48.00 MB/Sec Write Speed ~3.08 MB/Sec ~17.20 MB/Sec Common Failure Modes & Symptoms
ChipsBank devices rely on specialized software suites to initialize flash chips and partition bad memory blocks:
USB Flash Drive Speed Tests - VID = 1e3d, PID = 198a - NirSoft Usb Device Id Vid 1e3d Pid 198a
In conclusion, the device with VID 1e3d and PID 198a is a USB-based peripheral designed by Shenzhen Ezusb Co., Ltd. While I couldn't find any specific information about the device, it's likely used for a variety of purposes, such as software licensing, wireless connectivity, or data transfer. As with any USB device, there are potential security risks associated with the device, and users should exercise caution when using it.
. Because Chipsbank produces the controller (the "brain" of the USB drive), many different brands of low-cost or generic "unbranded" flash drives may share these exact IDs. DeviceHunt
The tool should detect the drive. Select "Production" or "Restore" to flash the controller firmware and format the NAND memory. Appendix A — Minimal checklist to run immediately
When a USB device fails to function properly on a computer, it often appears in the device manager with an identifier code rather than its brand name. One such identifier is . If you are looking for drivers or experiencing "Device Not Recognized" errors with this specific ID, this article will provide an in-depth understanding of what this device is, how to identify it, and how to fix related driver issues. What is VID 1e3d PID 198a? The USB Device ID consists of two parts:
This code points directly to Chipsbank Microelectronics Co., Ltd. , a semiconductor enterprise that specializes in flash memory controllers.
Chipsbank controllers are highly capable, inexpensive microchips designed for low-cost mass storage solutions. Because they are so cheap, they are overwhelmingly favored by fraudulent manufacturers overseas to create . As with any USB device, there are potential
Since this chip is often used in OEM products, visit the support page of your laptop brand (Chuwi, Teclast, etc.) and download the "Fingerprint Driver" or "Touchpad Driver" package specific to your exact model.
controller. You'll often find these controllers in budget or unbranded USB drives, including some "fake" high-capacity drives sold on online marketplaces. Common Issues and Solutions
