Usb Vid-0fe6 Amp-pid-9900 -

The hardware identifier USB VID-0FE6 & PID-9900 refers to the Corechip SR9900 USB 2.0 to Fast Ethernet Adapter. This specialized chip is commonly found in budget-friendly USB-to-Ethernet dongles used to add wired network connectivity to laptops, tablets, and desktop computers that lack a built-in RJ45 port. Technical Overview

The Corechip SR9900 is an ultra-low power, single-chip solution that integrates a USB 2.0 bus controller, a 10/100M Fast Ethernet MAC, and physical layer (PHY). Interface: USB 2.0 (High-Speed), compatible with USB 1.1. Speed: Supports 10/100 Mbps Fast Ethernet.

Power Management: Includes an embedded linear regulator (LDO) to reduce build costs and supports advanced power-saving states like ACPI and APM.

Features: Supports "Wake-on-LAN" (Microsoft Wake-Up Frame) and IPv6 protocols while in low-power states. Common Use Cases

You will typically encounter this device ID when using a "Plug and Play" Ethernet adapter on devices like the ASUSTeK VivoBook S15 or Lenovo IdeaPad Flex 5. It is a popular choice for manufacturers because it provides a reliable, cost-effective way to offer stable wired internet for video conferencing, gaming, or large file transfers where Wi-Fi might be unstable. Driver Installation & Troubleshooting usb vid-0fe6 amp-pid-9900

Most modern operating systems, including Windows 10/11, often include generic drivers that allow this device to work immediately upon plugging it in. However, if the device appears as "Unknown Device" in your Device Manager, you may need to install specific drivers.

Automatic Update: Right-click the device in Device Manager and select "Update Driver".

Manual Download: Official drivers are available from various hardware databases such as DriverIdentifier or DriverMax .

Cross-Platform Support: While primarily used on Windows (XP through 11), the SR9900 chip is also compatible with Linux and Mac OS systems, though manual configuration like usb_modeswitch may be required on some Linux distributions. The hardware identifier USB VID-0FE6 & PID-9900 refers

If you are experiencing slow speeds, ensure the adapter is connected directly to a high-speed USB port rather than an unpowered hub, as this chip relies on the 480 Mbps bandwidth of the USB 2.0 standard.

. This device is a budget 10/100 Mbps LAN dongle often used to add wired networking to laptops or small single-board computers. Arch Linux Forums Driver Installation Guide

Because this chipset is not always automatically recognized by modern operating systems, you may need to install drivers manually. For Windows (7, 8, 10, 11) For Linux (Ubuntu

The identifier usb vid-0fe6 & pid-9900 (often written as VID_0FE6&PID_9900) refers to a specific USB device: a USB 2.0 to Ethernet adapter using the DM9601 chipset (Davicom).

Here is a complete guide to identifying, finding drivers, and troubleshooting this device.

Driver Features

  • USB 1.1 speed (max 12 Mbps, real-world throughput ~4–6 Mbps)
  • Supports 10/100 Mbps Ethernet (but bus-limited)
  • No Wake-on-LAN, no VLAN tagging, no Jumbo frames

5. Use Cases

  • Legacy embedded systems (Raspberry Pi 1, thin clients, industrial PCs)
  • Temporary network recovery when built-in NIC fails
  • Low-bandwidth IoT or serial-to-network bridging (with additional hardware)

For Linux (Ubuntu, Mint, Fedora)

These devices generally have better plug-and-play support on Linux than Windows, but you need the right video software.

  1. Plug in the device.
  2. Open a terminal and type lsusb. You should see the ID 0fe6:9900.
  3. The Linux kernel usually treats this as a standard V4L (Video4Linux) device.
  4. If it isn't working, you may need to install the easycap kernel module: sudo apt-get install easycap-tools (commands may vary by distro).
