Do not use "Driver Updater" software from pop-up ads. They will break your system. Instead, follow these manual steps.
Step 1: Identify the exact hardware. Open the device case (if safe) and look for a small QFN-32 or QFN-48 chip labeled "CS-" or "CHIPS." If you see "CS198A," you have the right device.
Step 2: Download the correct driver.
Go to the official ChipSailing repository (or trusted mirror like libusb.info). Search for CS198A Driver Package v2.1.0. Note: This driver is often bundled with the "Zadig" tool.
Step 3: Install via Zadig (Recommended for Win 10/11).
Step 4: Linux & macOS.
Good news: Linux Kernel 5.4+ and macOS (with Homebrew) recognize this chip natively via the cdc_acm driver. Simply run:
sudo modprobe cdc_acm
Then check dmesg | grep 1e3d. It should mount as /dev/ttyACM0.
First, let’s decode the Vendor ID. The 1e3d code is registered to Chipsailing (often stylized as ChipSailing or associated with IC design firms in the Shenzhen technology sector).
Chipsailing is a fabless semiconductor company known for producing cost-effective bridge controllers and multimedia SoCs. They don’t typically sell keyboards or mice directly to consumers; instead, other manufacturers buy their chips to build products.
Based on driver databases, hardware forums, and USB ID repositories, PID 198A specifically points to a USB-to-Serial Bridge Controller or a Data Acquisition Module.
In practical terms, this ID is commonly found in:
Crucially: This device is not a standard USB flash drive. If Windows asks to format it, do not format it. You will destroy the firmware.
Many users find this error after a Windows reinstall. Your old driver might be sitting in the Windows.old folder.
