Usb Vid-0fe6 Amp-pid-9900 Guide

This specific product ID corresponds to the Corechip RD9700 USB 1.1 Ethernet Adapter (or SR9700/QF9700 clones).

If automatic detection fails, you will need to install the legacy Corechip/Kontron drivers manually:

The USB Hardware ID VID 0FE6 & PID 9900 identifies a Corechip SR9900 USB 2.0 to Fast Ethernet Adapter

: This is often caused by a corrupt driver stack or inadequate power from the USB port. Try plugging the adapter directly into a motherboard port (on the back of a desktop PC) rather than a front panel port or an unpowered USB hub. If the issue persists, completely uninstall the driver from Device Manager, restart the machine, and clean-install an alternate driver version. 3. Limited Speed Capped at 10 Mbps

If Windows doesn’t auto-install:

The system also detects and reports detailed device strings, identifying the manufacturer and product name.
