If your Linux terminal registers the device as a storage drive instead of an Ethernet link, you must install and configure the utility tool usb-modeswitch to force the hardware to flip from storage storage mode into network operation mode.

Windows 10 and 11 are very good at automatically finding and installing drivers for common devices.

💡 If you see "No Connection" even with drivers installed, check if the MAC address is being reported as all zeros ( 00:00:00:00:00:00 ). This is a common firmware bug in cheap clones. Configuring a static IP for this adapter? Fixing the "USB device not recognized" error? usb vid-0fe6 amp-pid-9900

USB 2.0 ports are usually preferred.

Usually, these devices work out of the box through Windows Update. If your Linux terminal registers the device as

Every USB device broadcasts a unique alphanumeric identifier to the host operating system upon connection. This allows the system to pair the hardware with its correct software driver.

Apple does not include a native driver for this chip. Third-party options exist but are increasingly unreliable on modern macOS versions (Ventura, Sonoma, Sequoia). This is a common firmware bug in cheap clones

The USB identifier VID_0FE6&PID_9900 is a classic example of the "long tail" of consumer electronics: a ubiquitous, low-cost chipset whose driver support is an afterthought. By now, you should understand:

Add a wired internet port to thin laptops lacking an RJ45 port. Replace a broken internal network card on a desktop PC.

Avoid plugging the adapter into unpowered USB hubs. Connect it directly to the motherboard or laptop chassis. 3. Reset the TCP/IP Stack

Here is why this cheap, ubiquitous chip deserves a moment in the spotlight—and why it might be causing you headaches.
