Specifically identifies the SR9900 model .
The USB VID-0FE6 and PID-9900 are unique identifiers assigned to a specific device or product that connects to a computer via a Universal Serial Bus (USB). These identifiers play a crucial role in enabling the operating system and device drivers to recognize and communicate with the device. In this article, we will explore the significance of USB VID and PID, understand the specifics of VID-0FE6 and PID-9900, and discuss their applications and troubleshooting tips.
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.
. This device is a compact network adapter used to provide a wired 10/100 Mbps Ethernet connection to computers lacking a built-in RJ45 port, such as modern thin laptops or tablets. Arch Linux Forums Hardware Identity Vendor ID (VID): (Associated with ICS Advent Product ID (PID): (Identified as the Manufacturer: CoreChips. Device Class: 10/100M Fast Ethernet. Driver Compatibility
. It’s a tiny piece of hardware often rebranded by dozens of different manufacturers, making it a "ghost" device that appears under many names but uses the same internal silicon. What Exactly Is This Device? The usb vid-0fe6 amp-pid-9900
To get your device functioning, you can look for the official driver package ( Corechip SR9900 USB2.0 to Fast Ethernet Adapter ) through trusted driver archivers or laptop OEM support pages:
Here is why this cheap, ubiquitous chip deserves a moment in the spotlight—and why it might be causing you headaches.
Some examples of devices that might use the VID-0FE6 and PID-9900 include:
. This cost-effective chip links modern computers lacking built-in RJ45 ports to wired networks. When operating systems fail to install the correct driver automatically, this hardware ID surfaces in the Device Manager alongside a yellow warning icon. Specifically identifies the SR9900 model
Today, it is a troubleshooting relic. If you have one in a drawer, it might save you during a Linux install or retro computing project. But for everyday use, consider recycling it and buying a modern USB 3.0 Gigabit Ethernet adapter (Realtek RTL8153 or ASIX AX88179) for under $15.

Right-click the device in Device Manager and select "Update Driver". In this article, we will explore the significance
The VID is usually represented in hexadecimal format, such as 0FE6, and the PID is also represented in hexadecimal format, such as 9900. When a device is connected to a computer, the operating system uses the VID and PID to:
Why keep one of these in your toolkit?
Because this VID/PID is widely cloned, the device may not be what it claims. Avoid using untrusted USB Ethernet adapters with this identifier in secure environments unless you have validated the chipset via physical inspection or advanced USB descriptors.
