If you're troubleshooting, try loading the dm9601 module on Linux or installing the LevelOne USB-0401 driver on Windows. This adapter is often used in older embedded systems, industrial PCs, or as a backup network interface.
The USB identifier VID: 0fe6 / PID: 9900 corresponds to a widely used USB 2.0 10/100M Ethernet Adapter, often based on the Corechip Semiconductor or Kontron (formerly ICS Advent) chipset. Device Identification
Vendor ID (VID) 0fe6: Registered to Kontron (formerly ICS Advent) or sometimes associated with Corechip Semiconductor in generic implementations.
Product ID (PID) 9900: Specifically identifies the USB 2.0 Fast Ethernet controller bridge. Driver & Compatibility
This device is a generic "No-Name" or "Blue" USB-to-Ethernet dongle frequently sold under various brands for laptops, tablets, and the Nintendo Switch.
Windows: Usually plug-and-play in Windows 10/11. For older versions, it often requires the Corechip SR9900 driver.
Linux/Raspberry Pi: Supported by the sr9900 or dm9601 driver modules. However, some users have reported stability issues (frequent disconnects or limited speeds) with this specific hardware.
macOS: May require manual driver installation for full 100Mbps throughput, as native support can be inconsistent. Technical Specifications Interface: USB 2.0 (compatible with 1.1/3.0 ports). Speed: 10/100 Mbps (Fast Ethernet). Protocol: Half/Full Duplex 10/100Mbps operation.
If the device is not being recognized, you can check its status in Device Manager (Windows) or by running lsusb (Linux/macOS) to confirm the VID/PID string.
