This report provides an overview of the CoreChip Semiconductor USB to Ethernet driver for Windows 11. If you have any specific questions or need further information, please do not hesitate to ask.
Finding the correct Corechip Semiconductor USB to Ethernet driver for Windows 11 can be challenging because many of these adapters use older hardware IDs that Windows 11 may not recognize automatically. While newer versions like the SR9900 have direct Windows 11 support, older models like the RD9700 often require manual installation of legacy drivers to function. Corechip Driver Compatibility for Windows 11
The compatibility of your adapter depends largely on the specific Corechip chipset it uses.
Corechip SR9900 (High Compatibility): This is the most modern chipset from CoreChips ShenZhen and features a dedicated Windows 11 Driver available on their official download page. It is often found in newer USB 2.0 to Fast Ethernet adapters.
Corechip RD9700 (Legacy): These are common in budget adapters. While officially dated, version 1.7.0.0 (July 2021) is reported as compatible with Windows 11 by third-party databases like Treexy and Outbyte. How to Install Corechip Drivers on Windows 11
If your adapter shows as an "Unknown Device" in Device Manager, follow these steps for manual installation: Identify Your Hardware ID: Right-click the Start button and select Device Manager.
Find the "Unknown Device" or the adapter under Network adapters. Right-click it > Properties > Details tab. corechip semiconductor usb to ethernet driver windows 11 top
Select Hardware Ids from the dropdown. Common Corechip IDs include USB\VID_0FE6&PID_9700 and USB\VID_0FE6&PID_9900. Download the Correct Driver: For SR9900: Use the official CoreChips ShenZhen site.
For RD9700: Search the Microsoft Update Catalog for "Corechip" to find verified older drivers that may still work on Windows 11. Manual Installation via Device Manager:
In Device Manager, right-click your adapter and select Update driver. Choose "Browse my computer for drivers".
Select "Let me pick from a list of available drivers on my computer".
Click Have Disk... and navigate to the folder where you extracted the downloaded driver (look for the .inf file, such as rd9700.inf). Follow the prompts to finish the installation. Troubleshooting and Performance Tips
Speed Limitations: Many RD9700 adapters are marketed as USB 2.0 but actually operate at USB 1.1 speeds (roughly 5–7 Mbps), which is significantly slower than standard 10/100 Ethernet.
Driver Disconnects: If the connection is unstable, try disabling "Energy Efficient Ethernet" in the adapter's Properties > Advanced tab in Device Manager.
Third-Party Tools: If manual installation fails, automated tools like DriverMax or DriverHub maintain databases for these specific legacy Corechip IDs.

Corechip Semiconductor USB to Ethernet Driver for Windows 11: Comprehensive Guide
Upgrading to Windows 11 often presents hardware compatibility challenges, especially for older or niche hardware like the Corechip Semiconductor USB to Ethernet adapters. If your internet connection has dropped or your device isn't recognized, you likely need a specific driver update to bridge the gap between your legacy hardware and Microsoft's latest operating system. Supported Corechip Chipsets for Windows 11
Most Corechip adapters use one of three primary chipsets. Ensuring you have the correct driver for your specific ID is crucial for stability:
SR9900 (USB 2.0): A common high-speed chipset found in many budget adapters. Drivers for Windows 11 are available and often require version 2.0.3.0 or later. Do not download from:
RD9700 (USB 2.0): Often found in older 10/100 Mbps adapters. While older, recent updates (version 1.7.0.0) have added official Windows 11 support.
QF9700: An legacy version of the fast Ethernet controller. Users often report better luck using RD9700 drivers if specific QF9700 versions fail on Windows 11. How to Download the Correct Driver
To get your adapter running, you should prioritize official sources or verified catalogs:
Official CoreChips Website: The most reliable source is the manufacturer's Download Page, which hosts specific SR9900 Windows 11 drivers.
Microsoft Update Catalog: For a digitally signed version, search the Microsoft Update Catalog for "Corechip." Look for drivers with a version date of 2019 or newer for the best compatibility.
Third-Party Repositories: Sites like DriverIdentifier or Treexy maintain databases for specific Hardware IDs like VID_0FE6&PID_9900. Step-by-Step Installation Guide

Finding the right driver for a Corechip Semiconductor USB to Ethernet adapter can be a bit of a hunt, especially since many of these devices are unbranded or "generic" imports. If you’ve upgraded to Windows 11 and your reliable internet adapter has suddenly gone dark, you aren't alone.
Here is a guide on how to locate, install, and troubleshoot Corechip drivers for the latest version of Windows. The Challenge with Corechip Drivers
Corechip (often identified as the RD9700 or SR9900 chipset) is a popular, budget-friendly solution for adding Ethernet ports to laptops. However, because Windows 11 has stricter driver signature requirements, older drivers that worked on Windows 7 or 10 often fail to initialize. Step 1: Identify Your Specific Chipset
Before downloading anything, you need to know exactly which "Corechip" you have. Right-click the Start button and select Device Manager Other Devices Network Adapters
Right-click the "USB 2.0 10/100M Ethernet Adaptor" (or similar name) and select Properties tab and select Hardware Ids from the dropdown. Look for the (Vendor ID) and (Product ID). VID_0FE6 & PID_9700: This is the common RD9700 chipset. VID_0B95 & PID_7720: Often associated with ASIX or upgraded Corechip models. Step 2: Where to Find Windows 11 Drivers
Windows 11 will often attempt to find a driver automatically, but it frequently fails with Corechip devices. 1. Windows Update (The "Optional" Path)
Settings > Windows Update > Advanced options > Optional updates
. Check under "Driver updates." Often, a compatible ASIX or Corechip driver is tucked away here. 2. Manufacturer Repositories
Since Corechip doesn't always maintain a consumer-facing website, many users rely on the Microsoft Update Catalog
. Search the catalog for "RD9700" or "SR9900." Look for drivers labeled for "Windows 10, Windows 11, and later." 3. Realtek/ASIX Cross-Compatibility
Many Corechip adapters are clones of ASIX or Realtek designs. If the Hardware ID matches an ASIX 88772 chipset, downloading the official driver from the ASIX website is actually safer and more stable than using a generic "Corechip" file from a random forum. Step 3: Installation Tips for Windows 11
If the driver installer (.exe) doesn't work, try a manual forced install: Extract the driver folder (if it's a .zip or .rar). Device Manager , right-click the device > Update driver Browse my computer for drivers Let me pick from a list of available drivers on my computer and navigate to the folder containing the Troubleshooting Common Issues "Device cannot start (Code 10)":
This usually means the driver is incompatible with Windows 11's memory integrity settings. Try turning off Core Isolation
in Windows Security, though this is not recommended for long-term safety. Slow Speeds:
Most Corechip RD9700 adapters are limited to USB 2.0 speeds (around 5–10 Mbps in practice). If you have high-speed fiber internet, the adapter itself might be the bottleneck, not the driver. Frequent Disconnects:
Disable "Allow the computer to turn off this device to save power" in the Power Management tab of the device properties. Final Verdict: Is it time to upgrade?
Corechip RD9700 adapters were designed for an era of much slower internet. If you are struggling with drivers on Windows 11, it might be worth investing in a USB 3.0 Gigabit adapter
(using a Realtek RTL8153 or ASIX AX88179 chipset). These are natively supported by Windows 11, requiring zero manual driver installation. Hardware ID (the VID and PID) from Device Manager?
